Let me just get this out of the way, I'm not a noob asking what 1-star weapons are the best, I'm a long-time veteran with eyes set on a few really weak weapons that I want to make as powerful as possible!
1 star weapons tend to lose their usefulness pretty quickly in Tier 1. Now I haven't extensively tested, but I already felt my Twack Hammer being too weak on Depth 3 on Elite difficulty.
So... what can be done? I'm thinking using a bunch of items with Sword Damage Bonuses, but I'm trying to look at 4-star at max here. How many different ways are there to increase Sword Damage? (Also, you can't stack those damage bonuses past "Low x 6", right? Aka "Maximum", effectively)
Also, would it be worth trying to get UV tickets for them, or is that a bit overkill?
Any other tips would be appreciated.
Oh, and how much extra damage do you get from leveling a weapon from 1 to 10? To me it seems to be around a 50% total increase.
