You concentrate a bunch of radiant energy on a target within range you can see. Target must pass the wisdom save. If the save fails, within a minute Arcane Mark applies on the target: all spells aimed by you at the target will deal an additional 1d6 Radiant damage if you can see the target.
If the save success, no additional effect is applied.
Arcane mark can only be applied to one target at the same time. Meanwhile, Arcane Mark doesnt need concentration. If you cannot see the target more than 1 round, the mark disappears.
If you apply Arcane mark to new target, previous effect disappears. If you successfully apply Arcane mark to the same target, previous effect will be renewed. If you fail to apply Arcane mark to the same target, previous effect wont disappear.
Arcane mark can be dispelled by any dispell magic effect.
The Mark's effect increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
