Harlequins' lore establishes no strict limits on how long their magicks can have their effects so I'm free here to assume that it can last for several hours at least, the entire battle for Sword of Orion will take about 6 hours, I suppose. She could enhance it and prolong its duration by pouring more amounts of her psychic energies on Victus but the current disguise can last for long enough without requiring her to "recharge" a spell.
Alright so, even if Victus makes it to friendly lines, is he going to still be in disguise? Considering he isn't, to the best of my knowledge, a psyker, he shouldn't be able to just turn off the spell then. Might make for some awkward discussion among the guardsmen
Yes, he still will be in disguise. And even if he were a psyker he would need to be an exceptionally strong one to remove Harlequin's spell, because usually even Eldar farseers or warlocks cant outdo Harlequins' magicks
Sorry for taking so long to post, holidays and such. Is it common knowledge yet that The Alpha Legion is supporting us? Sorry, I just can't recall and don't want to commit to either side yet.
Rejoice, Children of Stars, I sincerely hope it will be published in 2017 as soon as possible - it's a great misfortune we have so little number of Eldar novels and literally dozens about mon'keigh! Alas, for some reasons we dont have Necrons novels as well, only 2 short stories - 2 most interesting factions of Warhammer 40k universe and so few novels!
