Grad Cross with Erath Deleter Card

[oldschool_vinc]

Hello,
will the Earth Deleter Card work on Grad Cross skill? Because you get only SP for Physical  Melee dmg.

Reduces natural SP recovery by 100%.
Gain 10 SP each time an enemy is killed by a Physical Melee Damage.
Drain 100 SP as the armor is unequipped.

rms test it maybe? it certainly works with desperado, which is a ground aoe physical dmg spell

100% yes for Renewal mechanics. I don't remember if it did for pre-RE or not though.
