Experianced Warcasters are in high demand for Lords and on the Battlefield. But many are very vary Individuals not showing their Abilities lightly.

Astral Mind

Lvl3 Arcane avenger Feature

Once per Day you can Memorize one Spell from a Hostile Creature casting it. You need to see and hear the Target to Memorize that Spell. As long as the Spell is Memorized, you can cast it once and use Intelligence instead of its other Ability scores. After that you forget the formula of the Spell. You can Memorize every spell with this ability normally, as long as its Grade is equil or lower than your highest Spellslot. If the Grade is higher, than you can still memorize it too, but it strains your Mind to such a degree, that you cant cast Spells at your full Potential anymore. Meaning the highest Grade of any other Spell you can cast is reduced by 1, for each level the memorized spell exceeds your normal Spellcasting capability. But you can still upcast your spells and use your other Class features to access higher level Spellslots.

Example: The highest Spellslot you have is Grade 4, You memorized a Spell of Grade 6.  means: You cannot Casts Spells of Grade 3 or higher. ( 3 and 4 is too hard while memorizing)

You regain the ability to cast your Spells normally, after a long Rest without having a higher grade Spell memorized.
