Counterspell v 2.0

The target spell must be first level or higher and have a casting time of 1action.

Make a spellcasting ability check contested by the target's spellcasting ability check. You both get a +1 bonus to your check for every level you are casting your spell above your opponent's spell level or a -1 penalty to your check for every level you are casting your spell below your opponent's spell level.

The roll must occur no mater of the spell level being cast. The spell cannot be "Automatically stopped if its a first, second or third level spell".

This spell can not be up-cast at a higher level.

If the counter spelling caster has the spell hes countering memorized they get a +2 to their roll. The caster must : 1. know the language of the caster if verbal is a component to their spell. 2. Make an arcana check if the caster is trying to conceal his spell casting.

If the counter spell succeeds they effectively stop that spell from occurring leaving the caster the option of finalizing their turn or using the last few seconds to fire off a cantrip. The caster has the choice of attacking the original spell target or re-aim the cantrip at the counter spelling caster. In the case of a tie the casters must roll on the wild magic table (provided by the DM) to see how the magic has warped.

There is no countering counter spell.
