Trinity's Lament

You swing your two-handed weapon up in front of you, holding it vertically, and thrust it into the air. A glowing radiant yellow light is emitted from it, and a magically enhanced version of the weapon is made, extending out at over double the size of the original weapon. A Trinity Sigil is placed on the weapon, and every time a successful hit is made, one part of the sigil dissipates. Once all three sigils are gone, the magically enhanced form also dissipates.

Can make 3 successful attacks before the blade returns to normal. Range is increased by 5ft. All attacks made with the weapon gain an additional 5d6 + 4 Radiant Damage while the spell is active. Can only be used as an Action, meaning the blade can only be swung on the casters next turn and thereafter until the spell ends or until the weapon dissipates. Can only be casted once every 6 hours or up to 4 times every day at 6 hour intervals. If a critical strike is made with this spell active, roll the dice and add the modifiers of the base weapon for bonus damage instead of doubling the dice or damage.
