Signs are magical glyphs which a Witcher or spell-caster may weave (or incant) to conjure a variety of effects. Some signs are used primarily in overt combat while others are used in non-combat roles. Geralt has mastered five signs to use on his travels around the world.

Igni

The sigil of combustion. Used to ignite flammable material. This spell is essentially a standard fireball spell, doing first to third degree burns. Un-flammable enemies (like gargoyles and golems) may not remain alight as long as flammable enemies.

Sorcerers have been known to increase the potency of this sigil to call forth fire from the heavens.
