Rods

A rod is a magical cudgel, similar to a wand or magical staff but with some key differences. While each wand can only cast one spell and has a set number of charges, a rod contains one or more spells that are fueled by the rod's own self-replenishing MP pool. Like a staff, rods can be used as melee weapons, but their performance is only as good as a club without the stabbing bonus (though it does benefit from the Maces & Flails skill).

Any rod you've identified will be displayed as a "+X rod of descriptive_name (Y/Z)", where X is the recharge rate of the rod, Y is the current MP available for spellcasting, and Z is the maximum MP the rod can hold. Using a scroll of recharging on a rod will improve both X and Z by 1d2, up to a max of +9 and 17, respectively. Deep dwarves can use their racial ability for the same effect, although whether or not this is a wise idea is debatable. The rod's recharge rate does also act like weapon enchantment, so a +9 rod acts like a +9, +9 club; even with this, they are still usually terrible weapons.

Rods recharge themselves over time. The recharge rate depends upon both your Evocations skill and the rod's recharge rate. Base recharge rate is about 0.04 MP/turn, meaning that a +0 rod used by a player with 0 Evocations takes about 25 turns to regain 1 MP. Every +1 to a rod's recharge rate adds 0.01 more MP/turn, while every rank in Evocations adds 0.057 more MP/turn. These increases seem small, but add up quickly. A +3 rod and 13 Evocations adds 2 MP/10 turns, while a +9 rod used by a player with 27 Evocations gains 6 MP/10 turns.

Casting a spell from a rod differs from regular spellcasting in several important ways:

• Rods must be wielded before you can evoke them. Press v or click on the wielded rod in your inventory to cast a spell from the currently wielded rod.
• Spell power is based upon Evocations, not Spellcasting: Spell Power = 5 + 3 * Evocations.
• The rod spends MP equal to the spell level of the spell cast. This will regenerate over time independent of your MP regeneration.
• Hunger reduction works differently: rod spells have the same base hunger cost as regular spells, but this is reduced by 10*Evocations, instead of Int*Spellcasting. Additionally, spell hunger from rods cannot quite be eliminated: it is reduced to a minimum of 5, as opposed to a minimum of zero.

Tips & Tricks

• Maxing out rods may require more scrolls of recharging than you have on hand or aren't saving for useful wands. Nonetheless, it helps to at least tune useful rods up so that their max MP is an even multiple of the cost of the most frequently used spell.
• Most rods found laying around in the dungeon have mediocre or even negative recharge rates, but a rod generated by a scroll of acquirement will usually have a high recharge rate. So long as Evocations is your best magic skill, you are almost guaranteed to get a rod you don't already own if you request a staff.

As compared to spellcasting

Rods do have advantages over regular spellcasting, but they also have several shortcomings.

Advantages

• Rod use is independent of your stats. This allows a character which has focused entirely on Dex or Str to successfully cast some higher-level spells without having to resort to means such as wizardry or Ashenzari.
• Rod use is not negatively impacted by your EV penalty. Heavy armour users can use rods to gain access to some very useful spells if they're willing to train Evocations.
• Rod spell power is not subject to stepdowns: it simply scales with your Evocations skill.
• Rods do not drain your MP, leaving it free for other things.
• Spells from rods need not be memorized, possibly leaving your spell levels free for other things.
• Rods can be used while silenced.

Disadvantages

• Rod use is independent of your stats. Thus, high-stat races such as elves and demigods enjoy no advantage in spell power or hunger costs when using them.
• Rods have a somewhat limited selection of spells.
• Rods are ultimately capped at 86 power. This has a significant impact on higher-level spells like Iron Shot.
• Rods must be wielded to evoke spells from them. This significantly decreases tactical flexibility in using rods, and can prove a real danger if the rod should end up cursed somehow.
• The hunger cost of rod use can be very significant for some races. Trolls and spriggans in particular may want to use rods very sparingly, and any character should be cautious using them in branches which produce no edible corpses.
• Rod hunger can never be entirely eliminated. While the 5 nutrition minimum is generally ignorable, the minimum costs for L5 and L6 spells (80 and 280, respectively) from rods are not.
• Rods have a fairly small pool of mana, capped at 17, which can limit the usefulness of spells that you will want to cast repeatedly, such as Abjuration.
• Rods take up weight and space in your inventory, whereas spells do not.
