There are several ways to play the Serpent, but all require patience: early game involves slowly building up Powers and Presence. It's not helpless during this time, but it isn't as effective as anyone else. It becomes incredibly powerful after awakening, but getting there requires a lot of time. Make sure to Absorb Essence before you run up against your Presence cap - and to get other players' buy-in before using Absorb Essence on their Presence.
