first lets assume you defind 'tanky' as having lots of hit points + other defences both armour and resistences i.e, this characters main job is to take damage but not die
the most tanky class is Druid but Barbarian or fighter is a good 2nd
all 3 can also put out damage while being tanky but Druid takes longer to learn, barbarian is pretty simple and fighter is the most basic class
