Soloing from 54 to 60: tstaff or not?

[Hisamori]

I found a tstaff tonight. Walked in and warlord was holding it on second drawbridge.

So do I keep it or sell it? I am looking at it as a tool to reach 60, not necessarily as a raid weapon.

Other info: have fungi, epic, seahorse belt, SoS in bag and average droppable gear (BPS most slots etc.) Sitting at 20 weight with staff, have 2 tink bags. So not sure if there is anything significant I can buy with the coin.

The proc seems bananas so far, really cuts down mob dps. But is there any critical upgrades that might help I am not thinking of?

Thanks - His
