Paralysis

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

This page is about the status effect. For the monster spell, see Paralyse.

You are paralysed, and completely unable to act.

Paralysis is a status effect which renders a player or monster unable to move or act for a period of time.

Effect

When paralysed:

• Creatures are unable to act.
• EV is set to almost zero, 2 + size_factor, for players (plus any Repulsion Field mutation). For monsters, EV is set to 0.
• SH is set to 0.
• Monsters are vulnerable to high-tier stabs.

Once paralysis ends, players get a brief (1-3 turns) period of immunity to all sources of paralysis. Unlike sleep, paralysis doesn't end on hit. Unlike petrification, there is no special damage resistance.

Formicids are immune to paralysis due to their stasis.

Sources

There are several sources of paralysis. Some are resistible, while some are not.

Resistible sources of paralysis:

• The spell Paralyse, including wand of paralysis (2-5 turns for the player, must overcome the victim's willpower)
• The melee attacks of a hornet or jorogumo (1-3 turns; poison resistance blocks paralysis 2/3 of the time; poison immunity prevents it.)

Other sources are irresistible for non-Formicids:

• Stunning Burst (1 turn; 50% to resist with electricity resistance)
• Zot traps (2-5 turns)
• A floating eye's gaze attack (2-4 turns)
• Uskayaw's or Zin's wrath (2-5 turns)
• Cancelling Death's Door with Borgnjor's Revivification (2-5 turns)
• Stat zero (2-4 turns, ignores stasis)

Strategy

If a monster's paralysis can last for more than a single turn, it should be treated as instant death. Most monsters can kill you if you give them 4-5 free turns. Multiple monsters can definitely kill you in 4-5 turns. Even a single turn can cause a huge spike of damage. Having your EV and SH set to 0 is just the cherry on top; paralysis is nasty even for players with high AC.

Generally, you should avoid paralysis as much as possible. Even a < 1% chance of instant death is too much for streak play.

Tips & Tricks

Most sources of paralysis can be dealt with using one way or another:

• The paralyse spell requires line of fire. Spells can't be cast when a monster is silenced or waterlogged. Willpower can protect against it, though it takes high will to reach 0% success.

Racial willpower matters if you want to reach 0% paralysis. Against an orc sorcerer, a Human requires XL 19 and 2 external stacks of Will+, or 3 external stacks of Will+, to fully resist. An Ogre can resist at XL 14 with 2 external stacks of Will+.

• Hornets are fast enemies which can paralyse on melee. Wands can often kill or polymorph a hornet with some Evocations training. Lignification can make it very unlikely for a hornet to kill you by itself, due to Tree Form's rPois and increased AC.

• Floating eyes have an irresistible, smite-targeted paralysis that ignores willpower. However, floating eyes are frail, have almost no willpower of their own, and take a minimum of 2 turns to charge. Attacks that pierce enemies and never miss (such as lightning rods or Airstrike) are great. If all else, a scroll of fear has a 98% chance of working, allowing you to delay paralysis for a bit.

The teleport status still functions on paralysed players, though fear usually works out better.

• Zot traps require a monster to step on it, and the trap has to be in your LOS in order for it to function. Zot traps have a number of other nasty effects, so should be avoided if at all possible.
