I'd like to tack one more thing onto Regalia's overburdened body.
No, it's not an object. For once, it's a passive played straight!
Regalia's backside is constantly adorned with a cape made of multiple bolts of lightning, which he can channel through his armor to deal damage to attacker and target alike. They crackle and arc and sway as though they were a cloth cape, but disappear for a short time when he uses them to attack.
(20x3 = 80)
[20 Elec + Passive x4 cost]
I'll have 10 sig points left over after this.
