This is my solo build based on tactitian.
Key parts of the build are a weapon with Determined in the free slot, the Relentless Backpack, 5% of the damage dealt by explosion are return as healing, and the Barret's bulletproof vest.
406k skill power when I engage ; 370k when skills are on cooldown.
At 30 stacks skill power reach 507k and with talented activate 550k
