Predecessor Builds > Narbash > Narbash w/ emphasis on "bash"

this build is probably trash but i want to try it out later. In theory the idea is to be able to explore other ways of keeping the Song of My People buff going outside of the usual mana regen build, granted this build may not be the best it can be in order to best achieve that result (i want narbash to do more dmg for some weird reason). Anyhow I'm also looking to explore getting his cooldowns off quickly in order to make use of the item passives that proc off ability usage. I have no idea if it works but I'm interested to see how Ingenious Cleave and Crash Bang Boom work together, his Ult could do some pretty decent dmg in the right scenario, again in theory... unless CBB counts as a DOT which would be disappointing.
