[Spell] I need help to make this spells

[SoyMante]

If you can pass me the triggers in the comments or on a map I would really appreciate it.

for the first one you can just use storm bolt at melee range and change the values, and for the second one you can do the same thing with shadow strike.

#2 can alternatively be done with Acid Bomb if you don't want the green Shadow Strike numbers and sound effect to play.

#3 is just Devotion Aura + Enemy-targeted negative War Drums.

#4 would be achieved easiest by using Metamorphosis and transforming into an alternate unit-type. That alternate unit should have two unit abilities hidden in its ability list: Endurance Aura for attack speed and Critical Strike. You can properly set the level of all the relevant abilities on the transformed unit after it finishes the transform, but the health increase needs to be accounted for.

The easiest is just to use 3 alternate unit-types with the appropriately increased health, but alternatives exist. You could use Avatar but that gives spell immunity; you could use Robo-Goblin but that can't be a timed transformation (I believe); you could use item health bonus abilities but they can't have level-contingent values; you could use the ability field modification natives but that requires a recent editor; you could use a system like BonusMod but again that requires compatibility and an understanding of how it works.

Overall #4 is not complex, though.
