So many satisfying to play builds over the years. All of them nerfed or only became fun because they revealed a bug.
CC+wounding/puncturing wizard. Facloner Cleric that could insta kill orange names. Alchemist tank that could flash freeze everything cause breath weapon dc's unexpectedly added to transmutation dcs.
But what was the most fun was the suggestion tank or charm tank. It was a classic fighter tank, but with a splash of bard cause i was doing a scoundrel life, but decided to give it enchantment dc's good enough to use Suggestion to charm reapers.
This was back when charming a monster wouldn't strip a monster of their power and loved charming and dragging Carnage Reapers through the quest, buffing it and watching it destroy everything in its path! But the funniest part is when they'd break the charm and chase down party members. Often one shotting them if the reaper level was high enough and they weren't paying attention. XD
