Vehumet

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

"Let it end in hellfire!"

Vehumet is a god of the destructive powers of magic. Followers will gain divine assistance in commanding the hermetic arts, and the most favoured stand to gain access to some of the fearsome spells in Vehumet's library. One's devotion to Vehumet can be proven by the causing of as much carnage and destruction as possible. Worshippers of Vehumet will quickly be able to recover their magical energy upon killing beings. As they gain favour, they will also gain enhancements to their destructive spells — first assistance in casting such spells and then increased range for conjurations. Vehumet will offer followers the knowledge of increasingly powerful destructive spells as they gain piety. Vehumet likes it when you kill living beings, you destroy the undead, you kill demons, you kill holy beings and you destroy nonliving beings.

Given Abilities

Piety level -: "Sorcerer's Apprentice"

• No new abilities.

Piety level *: "Scholar of Destruction"

• Gain power from killing - When you kill a monster, you have a piety-dependent chance of recovering an average of (HD/4) MP. Specifically, you have a (piety-30)/piety% chance of healing 1d(HD/2) MP. HD is the hit dice of the monster killed. At max piety, you have an 85% chance. (Passive)

Piety level ***: "Traumaturge"

• Aid to destructive magic - Your chance of miscasting destructive spells is significantly reduced, equivalent to having 2 sources of wizardry.

Gifts

Spells. If you are above the first piety breakpoint and eligible for a gift, there is chance that Vehumet will offer you the knowledge of a Destructive spell. Vehumet will offer up to 15 spells:

Gift	1	2	3	4	5	6	7	8	9	10	11	12	13-15
Spell levels	1	1-2	2-3	3-4	3-5	4-7	4-7	5-7	5-7	5-7	5-7	6-8	8-9

The first gift will always happen at * piety. Once a new gift is offered, you lose access to the previous gift. The last three spells, which are all level 8-9, are all offered at once, and will always be available so long as you continue to worship Vehumet. Vehumet will not gift spells that are already in your library and will attempt not to gift spells that had been previous gifts.

Gifts will tend to correlate with your trained elemental skills. Investing more into specific elemental skills (Fire, Ice, Earth, Air) increases the chance of a spell of said skill. Each school starts at 100 "weight", and every skill level adds 10 to it; the relative likelihood of a specific element is (their weight / total weight). For example, if you have 10 skill in Fire Magic and 0 in other schools, Fire Magic will be twice as likely, and the others are 66% as likely.

Gift Breakpoints

Instead of the usual gift timeout system, Vehumet gives spells at the following points, assuming you have gifts left:

• Always gift at 30 (1*) piety for the first gift
• Always gift by 35 + (18*gifts_given) piety for gifts 2-5 (#2: 53, #3: 71, #4: 89, #5: 107)
• 5% to gift when gaining piety at >=120 (5*) piety for gifts 6-11
• 5% to gift when gaining piety at >=160 (6*) piety until no more gifts are left.

However, there is a cooldown of 98+2d50 turns for the first four gifts, and 128+2d50+2d15 turns for the rest. If you reach a gift point before then, the gift doesn't count. This isn't relevant for the gifts 1-5 (you'll always get the gift the next time you get piety), but it does matter for the 5* and 6* -based gifts. Once you reach 5* piety, it is optimal to wait 258 turns every time you get a gift - assuming you want gifts to be faster.

Therefore, an amulet of faith increases the speed of the first five gifts, and makes it more likely to gain piety. Therefore, faith only boosts speed by +25%, rather than the +33% of other gifts.

Punishments

Vehumet does not appreciate abandonment, and will call down fearful punishments upon disloyal followers! Those that anger Vehumet find destruction amply heaped upon them. Novices are struck by flame and frost; archmages by crystal spears and firestorms. Their own conjurations, too, are wont to misfire at the worst possible moments. Vehumet's wrath lasts for a relatively short duration.

Those who abandon Vehumet are periodically bombarded with a wide range of harmful Conjurations; various spells of a spell level between 1 + XL/5 and 1 + XL/3 are cast on you.

Vehumet also has a 5% chance to punish you whenever you cast a destructive spell. The spell still succeeds, but you get a miscast effect anyway.

Strategy

Vehumet offers a nearly guaranteed "engine", or way to kill things up through Zot:5. However, it lacks the active abilities of other gods, making you worse in emergencies. In a way, you aren't worshipping Vehumet; think of your spells as the actual god.

The curated spell gifts, starting from 1* of piety, ensure some method to kill those pesky orbs of fire (and just about everything else). Two free ranks of wizardry help get your powerful spells online faster. It makes level 9 spells reasonable to cast in a 3-rune game. And the +1 range is helpful for certain spells. All this comes with zero Invocations investment. Combined with the wizardry, and worshippers can afford to invest more into defensive skills, or even hybridize.

Whether "having spells as a god" is a good thing is up to you, but it does come with a few downsides. Without active abilities, you have less ways to deal with a dangerous situation. And, Vehumet is one of the weaker gods for the early game. For spellcaster backgrounds, the first few spell gifts generally won't be much of an improvement compared to your own spells. Those new to spellcasting have to take time to train up magic, which might not be all that powerful by the time you hit 1* or even 3*.

Overall, Vehumet is deceptively simple. Your spells may be strong, but good general play is still necessary to make up for a lack of actives.

Tips & Tricks

• The MP refund is fairly weak early on, but really shines with higher-level AOE spells that take out multiple enemies at once. Vehumet doesn't even require you to use spells; bashing them to death with a magical staff or firing a wand works just as well.
• Since Vehumet will try to gift spells which you haven't yet seen (picking up a book will mark all spells therein as "seen"), it may be worth buying early spell books from magic schools you don't want.
• Vehumet is one of the few gods you can abandon while keeping permanent benefits granted via worship (spells learned via direct gift).
  • Vehumet is a decent god for the extended game, thanks to the strong MP regen, but a god with useful active abilities may be preferred. For example, The Shining One provides active abilities and both HP and MP restoration when killing evil monsters (which make up most of the extended game monster lists).
  • Vehumet is actually one of the stronger Ziggurat gods, as the sheer mass of enemies you'll be killing provides a massive amount of MP.

History

• In 0.26, Vehumet's spell gifts were widened in level range.
• Prior to 0.16, Vehumet tried not to gift spells that could cause antitraining (Fire/Ice, Air/Earth).
• Vehumet underwent a complete overhaul in 0.12, dropping summoning support, MP cost reduction, and book gifts, instead gifting destructive spells directly. For information about Vehumet prior to 0.12, see this revision.
