Gale Sanctum is the 2nd mission which requires to complete Windswept Peaks. It is not hard to complete on Adventure difficulty. The boss Tempest Golem is not hard to kill, it's really boring because he has 2 types of attacks and push you back so..
Tips:
- You should have a pretty cool bow (I recommend
Super Charge and
Multi Shot)
- Pick the artefacts like
Lightning Rod, or
Fireworks Arrow- If you have wolf, golem, or lama with
big power you can use them, because if you stay far from him he will not attact them so the will able to hurt him don't stop
- Do not clear these
"totem" things, there are 2 of them if you clear them the other golems will wake up
If you do not know how Tempest Golem look here is the picture -
I could not find anything better!! If you gonna need help I play minecraft dungeons often so you can add me
Best of luck!
