I play TERA Online, Tribes: Ascend, DOTA 2, Bloodline Champions, Minecraft, League of Legends, Super Smash Bros, platformers, fighting games, RPGs, you name it.
For TERA BAM soloing I use 2x anarchic and 2x vigorous blue crystals and forceful, focused, savage, and glistening red crystals. Most are store-bought and the main reason for this is because it takes quite a few runs to learn or re-learn a BAM's moves and I prefer to use crystals I can easily replace for this. Keep the uncommon crystals for hard mode runs where they matter most.
Notable glyphs are Sanative Combative Strike, Lingering Traverse Strike, Empowered Rain of Blows and Blade Draw, Persistent Blade Draw, cast speed on Pounce, mana back on Combo Attack, and cd reduction on DfA. I think I will also spec into Carving Scythe, since the burst from that is very high.
