You can channel your inner magic to summon allies.
Prerequisites
Elemental Bloodline (Water Elemental), Hydraulic Push, bloodline level 2nd.
Benefit
You may expend two uses of your hydraulic push spell-like ability to instead cast summon nature’s ally III as a spell-like ability with a caster level equal to your bloodline level. This use of the ability can only summon 1d3 Small water elementals, 1d4+1 dolphins, a shark, or an electric eel. Using this ability is a full-round action.
