aSeamus with WP Buffs

[whitefire]

ok if I take aSeamus with sue and an orian can i use Succumb to Darkness more than twice in a match? It receives -2 WP and increases its terrifying until the end of the Encounter. This model cannot perform this action if it would reduce its WP below 1

All it says is is the model can not perform the action if its wp would reduced below 1. It says nothing about maintaining its WP at or above 1.

Yep, I'm pretty sure you can. Whether or not it's a good idea is another question, but yes, I think you can wind up with a super-Terrifying gibbering monstrosity of low Wp.

Sue's ability only increases the Wp of the affected model during opposed duels and not the general Wp statistic. The Oiran is a different story but she only gives +1. So in this case I would say no, you can't use it more than twice.
