Alek'sei's Crimson Forge

You summon a giant forgemaster from long ago, which reviews and either improves or shatter workings of metal.

When casted, a 30-feet radius around you can be affected by two choices-

Brittle- Every enemy that you can see within the radius needs to make a Strength/Dexterity saving throw (depends on their attacking stat), and get a bonus to that saving throw from any bonus affecting the melee weapon (such as, an enchanted weapon with a +1 will recive a bonus of 1). If they fail, they have to roll with a -2 to attack. If they succeed, they aren't under penalty. If they start their turn inside the radius, they have to make the saving throw again.

Sturdy- Every ally you can see within the radius recives a +1 to attack. If the ally doesn't start his turn inside the radius, he will lose the bonus.
