Endgame?

[LunarEmerald]

Relic weapons are the best weapons available. +1 being a tiny buff to it. Relic weapons require beating all 3 HM primals. So yeah, you won't be getting relic anytime soon. Grind tombstones for better gear and get a primal weapon if you're lucky.

Weapon
1. Relic+1
2. Relic
3. Primal (Garuda's is the best one of three)
4. Grand Company

Equipment
1. AF2 (need allagan tombstones of mythology)
2. Darklight (need allagan tombstones of philosophy)
3. Amdapor Keep loot
4. AF

Crafted equipment can be better than AK with melded materia but it's really not worth the effort.
