Doesn't Time Temple require Maker...?

Cursayer yes, a dozen other level 90 weapons... no. So good if you're a STR bandit (all 3 of them) but not so much for anyone else. Most of the 90 weapons came out with Ludibrium, because we still didn't have Zakum at the time.

& I'm not sure what you mean with the other part about Zakum being created later, Zakum was out in KMS/JMS before global even existed.
