Ideas for the other 2 dark spells

My thoughts for the 2 spells are :

1. A Protection spell that protects your troops inside it from the defenses inside it , but not from the defenses inside the spell like skeletons and so on. It could have 4 levels that increases the duration of the spell starting at 1.5 Seconds and increases 0.5 seconds per level to a maximum of 5 levels.
2. A Weakening spell that weakens the defenses inside it for an amount of damage and rate of fire. For example, weakens the damage per second from the defenses by 20 and the attack speed by 30%. for its upgrade it could increase in damage reduced and slow effectiveness starting from 15 damage reduced and slow by 20% from the rate of fire and increases by 5 damage reduction per level and 3% extra slow.

Numbers and levels are open for you guys to adjust it
