the Tarrasque is the king of "CR and Encounter building doesn't work" if your party is made of experienced gamers, has the slightest bit of luck and just the basic items that you would find in a WOTC adventure, they can take him down at 10th level... If they are power gamers with good stats and/or good items by 7th level.Yes, it's a real shame that my level 2 PCs slaughtered a herd of tarrasques, it should only have been hyper-deadly x99 for them, and still, it was over in one round. Shame on WotC, honestly ! What ? What if my PCs had their stats rolled on 2d100+100 ? What does this have to do with the result ? And no, they did not have magic items, because artifacts are not considered magical !![]()
