Legend
my warlock/Sorcerer PC did something like this... she cast simulacrum from an item on herself. had her simulacrum use the item the next day to cast simulacrum on the barbarian... we went into the last 5 adventures (we were level 20+ boons by then) with 'not tasha' and 'not grahl' taking point.The BBEG was a 20th level wizard with a simulacrum. The party consisted of the following:
Half-orc Fighter/Rogue 15/15
Dragonborn Barbarian/Fighter 15/15
Dragonborn Sorcerer/Druid 15/15
Human Paladin/Cleric 15/15
Human Monk/Druid/Wizard 12/12/12
Half-elf Bard/Monk 15/15
High Elf Cleric/Rogue/Wizard 12/12/12
We did a variant of old school multiclassing, so each PC had the experience required to be equal to a 19-20th level character. With our MC rules, each had 19-20 HD, not 15 or 12 as you might think.
The final "adventure" (worth about 600,000 xp) was being summoned to the wizard's island domain and defeating numerous powerful foes before assaulting the wizard's stronghold. They found and destroyed the wizard's clone before defeating his simulacrum, which they believed was actually him. The wizard toyed with them prior to all this, using his magic to restore to life to two of the PCs who died against some of the wizard's minions and traps. It took six sessions (8-10 hours each) to finish it.
Sadly, the game ended with them believing they had won. They never even fought the wizard, only his simulacrum. Little do they know the NPC warlock who was helping them was actually the wizard. By helping the PCs recover his love, the Elven noblewoman, from the vile "wizard" and "defeating" the wizard, the wizard has really positioned himself well to marry the noblewoman and eventually take over the Elven Court, solidifying his world power even more.
The entire quest for the PCs was a ruse for the wizard to gain even more power. The players believe they have won, but this twist leaves it open for me to bring those PCs back for some "epic" adventures...
what in game no one knew (out of game everyone did) was that I had my lover cast simulacrum on me too (useing the 3rd wish from the ring) and as such the 'real' tasha in the adventure wasn't me... I was back home in my tower.
now the 'real' me never died... but if she had boy would that have had some shocked faces in game.
back in 3e I had a villain that used Simulacrums, clones, and apprentices with illusions up so often that one of my players around the 4th or 5th time they killed him broke character and quoted a FF comic "I'm starting to suspect there is no real doctor doom, just doombots"
casters and non casters are bearly playing the same game at high level
