Offense is a skill tree in Ars Magica 2, found in the Occulus, along with Utility and Defense, the other active skill trees, and Talents, which is a passive skill tree. It is used for, as the name implies, more offensive spells, including things like Projectiles, Area of Effects, Beams, or even Waves of all sorts of different damage types.
The tree includes the following, from top (easier to get) to bottom (harder to get).
Shapes: Projectile, Contingency: Fire, Area of Effect, Beam, and Wave.
Components: Physical Damage, Forge, Ignition, Fire Damage, Lightning Damage, Frost Damage, Magic Damage, Drown, Blind, Freeze, Knockback, Astral Distortion, Storm, Silence, Fling, Watery Grave, and Fury.
Modifiers: Gravity, Bounce, Piercing, Solar, Velocity Added, and Damage.
Silver Spells: Blizzard, Starstrike, Firestorm, and Dismembering.
Some of the more useful items in here are the Shapes of Projectile and Area of Effect, the components of Damage Types, along with Forge and Ignition, maybe even blind, and the Modifiers of Damage and Bounce, although all of these shapes, components, and modifiers can be used to great effectiveness if they are used correctly.
