Charge Focus

You transmute  an arcane focus into a charged magical weapon using the power of a damage dealing cantrip you can cast. While the focus retains at least one charge, it is a magical weapon in which you are proficient that allows you to use your spellcasting ability instead of Strength or Dexterity for the attack and damage rolls for weapon attacks using the charged focus.

The charged focus can hold a maximum number of charges equal to your character level. A single use of this spell fully charges a focus. A focus cannot hold charges from more than one character or specific cantrip.

Each charge can be used to add a die of damage to castings of the same cantrip used to charge the focus or to weapon attacks with the charged focus. The type of damage and die size are determined by the cantrip charging the focus.

The material component for this spell is an arcane focus which must be a rod, staff, wand, crystal, orb or a weapon with an attached Ruby of the War Mage. It cannot be used on any other type of arcane focus.

 In addition, a charged rod, staff, wand, crystal or orb constitute simple weapons with the following statistics:

Rod- 1d6 Bludgeoning, light

Wand- 1d2 Piercing, finesse, light

Staff- 1d8 Bludgeoning, Versatile(1d10)

 Crystal or Orb- 1d4 bludgeoning, light, thrown (range 20/60).

If a charged Crystal or Orb hits its target when thrown, it shatters and discharges all remaining charges. The total magical damage from the magic grenade discharge is split equally among all characters within 5' of the primary target that fail a Dexterity save.

If a character other than the caster wields the charged focus in combat, the weapon uses the caster's PB and spellcasting ability modifier instead of their own PB and Strength or Dexterity modifier. In such a case, the focus automatically discharges 1 charge each time it hits.

A focus which retains at least 1 charge for a year becomes a permanent magical weapon without charges with the above described properties. The permanent weapon created in this manner has a magical attack and bonus dependent on the level of the  caster of the final casting of this spell; level 5 or less: +1, level 6 to 10: +2, level 11 to 15: +3, level 16 to 19: +4, level 20: +5.
