Accelerate your magical tempo to unleash multiple attack spells in a single round with reduced penalties.
Roll d100 versus DR100
Success: Subtract 10 from the penalty for each extra attack plus gain an additional -5 modifier per 10 points of success rate
Failure: You have disadvange on your next Fatigue Threshold roll (roll twice - use lowest)
-10 to DR if you casts spells within the same category
+10 to DR if you change category
(if you cast the same spell, you will face the -25 combat modifier of recasting attack spells as well as the penalty to cast multiple attack spells, but that modifies the spell - not this skill).
You cast Lava Eruption followed by Incinerate Orb and you roll a 120 total on your skill check. The second spell's penalty is reduced from -50 to -25 (DR is 90 because you stayed in the same category).
Quickened Casting lets combat mages break traditional action limits. It channels deep familiarity and mental agility into an offensive tempo that overwhelms slower foes. While no spellcaster can completely ignore the strain of multiple casts, this skill allows them to shave penalties and make two or even three attacks feasible within one round.
The reduced penalty only applies to attack spells (as spells cast as a defensive reaction do not have the attack penalty), and requires a lot Action Points to support multiple casts. Tactical positioning, target selection, and storing up Action points are key. If paired with Delay Spell, Phantom Casting, or Spell Feint, the result is unpredictable and hard to counter.
It also synergizes well with:
Will often be to expensive to sequence, but consider any of the above mentioned skills.
Counterspell, Dispelling Strike (if the spell requires concentration), Evade Spell Attacks and similar are direct counters.
