here are my ideas
crystal bomb: leave it as it is
ss and rss: the same with undead bonus making it the ultimate weapon against monsters that do shadow damage
RSB and ISB: change piercing damage to shadow, remove the chance to shock, make it have the same charge time as RSS and SS and give it bonus to slime and constructs.
Thank you there are my ideas
Radiant Sun is fine as it is. Anyone who has it knows every reason why.
Salt is supposed to be a neutral alternative to Sun, even though having split normal damage with pierce does not always compensate; the shock and elongated charge time are meant to force the user into "assassin" tactics, sneaking up on something while charging then tasing them with it.
Way ahead of you.
