Binding Ritualist's create all there spirits at the start of or before combat.
Energy consumption is greatest during this breif period in time.
After construction has been completed on these spirits, a ritualist will have little to do while their spells recharge.
If your finding that you dont have enough energy to cast all your spells at once, heres the trick
Get your energy from 45 to 72 using weapon combos

Weapon Set One: +60 Health combo

Weapon Set Two: +30 energy -2 energy degeneration

Use weapon set 2 while creating your spirits when energy is in greatest demand

Use weapon set 1 in combat for health bonus
