Temper

The spellcaster focuses their energy on a ally member and when the spell is cast it enhances the ally's STR or DEX for a certain amount of turns equal to the spellcasters proficiency, the STR or DEX modifier of the ally is boosted by the spellcaster's own spell modifier. as soon as the spell's been cast then the spells effect stay until the amount of turns equal to the spellcaster's proficiency or dispelled. When used on a spellcaster then any spell the spellcaster uses will gain advantage in the attack roll and use two extra dice in their damage rolls of whatever dice is needed for the damage. (note: if used on yourself the first turn when the spell is cast does not count as a turn)
If cast at higher levels then the ally affected will get the following effects.

At 6th level the ally gains a hit DC bonus equal to the spellcaster's "spell attack". While used on a spellcaster instead they will get three extra damage dice.

At 7th level aside from the effects from the 6th level form, the ally's STR or DEX modifier is considered doubled before the spellcaster's modifier is added. While used on a spellcaster instead they will get get four extra damage dice and immunities are treated as resistance instead and resistances are treated as neutral.

At 8th level aside from the effects from the 7th level form, the critical chance is lowered by the spellcaster's spell modifier. While used on a spellcaster instead they will get five extra damage dice and the spellcaster is allowed to reroll any damage dice the amount of times from the spellcasters proficiency as long as it's below the spellcasters proficiency number.

At 9th level aside from the effects from the 8th level form, the "spell attack" modifier used is doubled for the hit DC bonus and the damage. While used on a spellcaster instead they will get six extra damage dice and neutral will now be considered a vulnerability to the damage type as well as the proficiency limit from the reroll number is now any roll the spellcaster wishes to reroll.
