Warding Against the Gods

This spell is 3 spells in one.

It will let you ward against one of the pantheons using the blood of a god from the pantheon you want to ward against and requires a Dc 18 Arcana check to ensure the warding is successful. If you fail the roll the DM has to make a d100 Dc 50 roll for the warding success and does not have to tell the party if it succeeds. This is to create four totems that you place in the cardinal directions with hieroglyphs, runes or enchantment on each object for each respective pantheon as to the blood you collected. You then walk around the perimeter of the location you want to ward while placing objects in the cardinal directions and drawing a line between them. The line doesn't have to be straight or a line at all, it could be a wall or an enclosed area, as long as it doesn't exceed the 100 ft radius of the spell.

It can also be a small circle if you take the time to prepare the items in advance, but it only works on the respective pantheon as the blood you use to draw the spells on the totems, and in that case, the spell takes five actions to cast. The first 4 are placing the objects in the cardinal directions, and the last is speaking a chosen activation word. 

The ward appears instantly after the spell is activated, and any god from the chosen pantheon can no longer enter that area. The ward has the same health as the caster at full health and will retain the resistances and immunities of the god the blood is from.
