Still Spell?

[sineater]

Ok if a wizard has a chain shirt equipped it gives him a 20% Arcane Spell Failure chance. But if he has Still Spell, would that cancel out the 20% chance of failure. Since he doesn't have to move anymore to cast a spell due to having Still Spell.

If it doesn't cancel out the percent chance, Why?

 

[coyote6]

If a wizard or other arcane spellcaster casts a spell with a somatic component, any arcane spell failure chance they may have (from armor, shield, heavy load, etc.) applies. If they cast a spell without a somatic component, arcane spell failure doesn't apply.

Still Spell removes the somatic component from a spell. So no need to worry about arcane spell failure for Stilled spells.

PHB, p105 (Arcane spell failure)

If the spell lacks a somatic (S) component, however, you can cast it without making the arcane spell failure roll.

p85 (still spell)

A still spell can be cast with no Somatic component

So, no arcane spell failure for stilled spells.
