What are people using for a sentient weapon at levels 29, 30 and why?
I am having a hard time seeing any obvious choice for a palemaster. Spell power and spell mastery come on so many items aside from a weapon. I have no trouble fitting in nullification/lore on wearables... lets assume a Legendary Styigan Wrath so the insightful nullification/lore is accounted for too. Those generic ml:29 sceptres with spell mastery/penetration (+insightful) could have been candidates but wearables cover those too.
My default choice is to just keep using the ML:20 borderlands epic sceptre of nullification with a lot of sentient xp in and would prefer to keep for epic levels anyway. It adds nothing beyond the sentient bonuses but would save the trouble of building up a new higher level item with sentience. Are there obvious high level main hands for casters and/or palemasters that I've overlooked which would make a significant difference?
What about something like Legendary Celestial Beacon to increase damage from shiradi light procs? Would that make enough of a damage improvement to justify plugging in another 40 or 60k sentient xp?
