GM: for a total of 47, dealing 70 damage and you are grabbed.
GM: for its other 5 attacks ...
My favourite is its reflect ability. If the players pull some meta bullshit like dropping tungsten rods from orbit the tarrasque can just play an uno reverso card and nuke the players.
I had the idea to do the reverse and throw the 5e Tarrasque at my players in my PF2e when they are around level 8* or so. Basically using one of the most powerful DnD bosses as a mid level side boss.
