Citadel Gate

A gate of stone rises from a square area of ground of your choice within range. The gate is 105 ft tall , its pillars are 45 ft wide each, and the space between the pillars is 60 ft across (with a total width of 120 ft), and it must not have any buildings or other structures on it. Any creatures in the area are harmlessly lifted up as the gate rises. The gate has 140 hit points and has resistance to all nonmagical damage.   When you summon the gate, each creature that is an ally to you and is within 20 ft of the gate automatically gain 1d6 temporary hit points. 

While or when you summon the gate you can choose to grant it two of the following effects:

• Each creature that shares your alignment and religious belifs that are within 40 ft of the gate gain a +1 bonus to Armor Class.
• Once per day, if you are alive, you can cause the gate to force each creature within 15 ft of it that are hostile to you and/or your allies to make a Dexterity saving throw, taking 1d4 psychic damage plus 3d10 radiant damage on a failed save, or half as much on a success.
• Each creature that shares your alignment and religious belifs that are within 40 ft of the gate gain a +1 bonus to attack rolls.
• Each creature that shares your alignment and religious belifs that are within 40 ft of the gate have every one of their speeds increased by 10 ft.
• Each sentient magic item that shares your alignment and religious belifs that is within 50 ft of the gate can cast (or allow for its wielder to cast) the detect evil and good spell once per day.
• Each sentient magic item that is evil-aligned that is within 40 ft of the gate cannot have its activated abilities activated by evil-aligned creatures.
• Evil-aligned creatures that are within 40 ft of the gate have a -1 penalty to attack rolls and ability checks.
• Once per day, if you are alive, you can cause each creature that shares your alignment and religious belifs that is within 40 ft of the gate to gain the benefits of a bless spell.
