I think transformation scroll sprite changes should not be allowed during woe.
GMs already disabled costume and pets, but you'll allow sprite changing... isn't that worse?
You can keep the effects, but i say the player sprite should not be changed inside castle.
mechs and Warlocks can stasis or suicide and disable/kill large groups of people, and classes that try to stop them cannot stop them cause they're busy looking for those classes, not a deviruchi or a poring.
For example, a large tactical strategy would be to spellbreak stasis and suicide. Thats close to impossible when you're not expecting a devi or poring to do those skills.
And its pointless to spam spell break on a deviruichi because it could be ANY class, such as a high priest.
Its not a fair advantage for anyone with scrolls, as the people defending against it dont' know what to assume.
