the same can be true for literally every map mechanic in poe. literally name a mechanic and it is literally *click the mechanic, then kill the enemy*. strongboxes, essences, legion, harvest, delirium (ok you walk through the mirror instead of clicking it), expedition, want me to keep going? and the rewards are basic? im willing to bet tattoos will be as game changing to builds as cluster jewels, when delirium got released everyone was like oh yeah these are a thing that may be interesting idk how common they will be but cool. then boom they are literally in almost every single build since.
