I've been more successful than I anticipated on my homebrewed power siphon totems build and wanted to show it off a bit as well as get some help. I haven't had a lot of time to play so I've been pretty broke, and to be honest it hasn't been the best starter for making money, but all things considered the build has been pretty good to me. At this point I've probably spent about 2 div total, and have been easily doing the league mechanic in T16 maps (not super juiced, but no issues even with delirium mirror and abyss). It's been extra easy to gear because Aegis Aurora is dirt cheap this league.

The idea was to stack mana and get tanky with the classic Memory Vault/CI/Aegis combo, while at the same time getting reasonable dps on power siphon. Since I have a lot of mana regen (from 6 totems with the Hiero passive), I went with Lethal Pride/Chainbreaker for almost 100% berserk uptime, while at the same time fixing my strength issues. I have two rings with -mana cost to enable this. Rage/Berserk makes me super zoomy and even more tanky, making for great mapping. When I have a little bit more money, the plan is to get the guardian forbidden jewels for even more ES and armour, but honestly tankiness has not been a problem at all.

The main problem right now is that the single target DPS is fairly abysmal, I have about 1.2m dps with all 6 totems down and spamming frenzy for frenzy/power charges. I'm hoping someone who is better at the game than me will have some ideas about how to get substantially more dps. With a few more levels and money, I should be able to get maybe double the dps, but I would ideally like to get 5x the dps or more.

Please PoB warriors, save my build, I'm hoping I can take it to the end game but the single target is a huge limiting factor right now.
