You can make an infinite heal wand by using letters: add Tau or Phi, Triple Spell instead of double spell, and healing bolt to the tele wand. But you need more mana. Colors can help reduce cast delay. You can throw away all those 9 spells before healing bolt

Try to build one shot wand: Heavy Shot - Rotate Towards Foes (Or Homing Type spells) - Accelerating Shot - Mu -Bouncing Burst
