Not sure if this is intended but for those who play ele sham, the best shield you can get is the phase 2 blood moon shield (haven’t seen a shield that drops in sunken temple). However a very important relic/totem that increases flameshock range by 5 totem of fiery precision is also from blood moon but costs the phase 3 coins instead. I find it bizarre and unfortunate that we can’t use two blood moon items that are of completely different phases, and will most likely have to use a worse shield to use a relic.
Edit: There is a healing shield from ST from what I’ve seen drop so maybe there is a caster shield as well.
