I do not see the point in this at all, Its a waste of componants especially as its no drop.
I have found 2 now, Both Illusion Barbie, There may be a link between the illusion and the theme (both mine were from Tak) or the link could be with the caster who unlocked the chest (ie me being a Barbie Shaman unlocked both chests and got a no drop illusion Barbie potion - just what I've always wanted....). Or I just got really lucky or the random potion roll.
When Sony recently messed with the LDoN zones (making Everfrost easier, and ******** Necromancers / Paladins in Mistmoore) they also claimed to be altering the contents of chests / barrels to make them more worthwhile. The old chests could yeild as little 4 gold, and no items, but now, rather than compensating casters for an 18 plat componant, they give us these as a consolation prize. I think Enchanters value these the most, they spend their hard earned points on spells that make available potions that make their fun spells unnessecery. <random rant>
Anyway, the illusions are of all races, but are only found in chests / barrels. If you're into pretneding you're another race, do Grieg's end instead, more variety :p
OOOOkay...so what's the purpose here? Ya can get illusion potions from your friendly neighborhood shaman that are tradeable. Maybe they're trying to get the shaman community up in arms or something...
I believe these are completely random for the race the illusion provides, as my guild has seen many different variations of this item drop (all from chests).
