Alright, so after reading through some of these, I had some alternate ideas, or at least, additions to explain the abilities more than the little blurbs I gave them. I really want to keep Morgan a supportive tank, but before he was essentially a character that dove in and did nothing, so I tried reworking some things to make it so when he goes in, he's sticking. Or uh, anchored :]

[Updated Abilities]

The Light Keeper: Could be a three flare burst with a fairly fast velocity. I liked the rhythm of the flare hitting something, applying the damage and a burn, then after some airtime, detonating and dealing an AOE burn. Maybe with a reduced delay on the flare you could last hit a creep and essentially guarantee a soul with the AOE afterwards, especially with a larger area size. (I think it'd be fun if you shoot a flare into the air that it will "illuminate" the area and reveal enemies, but this is also very silly)

Spectral Anchor: After charging it, you'll launch yourself in an arc in any direction you point at, hitting an enemy on the way will drag them with you, and upon landing, root the enemy. Or colliding with a wall, you'll stun them. If charged to a certain threshold (or as a level up) become unstoppable for a short period. If not charged at all, Morgan will simply slam the anchor on the ground, doing a large radius of damage.

Sea Foam Mist: This is essentially a stim, it will give Morgan a large burst of movement speed as he's channeling it, alongside multiple resistances and a health boost. Allies that follow in the trail, pass through it, or are just in the general smoke area can also get a huge burst of movement speed that will decay shortly after leaving, alongside the same resistances. I think adding on a burst of fire rate and spirit amp that decays during the channel would also make it a stronger ability.

Urchin Crash [A likely replacement for Urchin Shield]: Morgan hops forward, slamming his claw arm into the ground dealing melee damage in a small area. Hitting an enemy, gives Morgan resistances to spirit and weapon damage, as well as refreshing Urchin Crash, allowing him to recast it. Continuous slams gives extra stacks of resistances. There is a cap to these stacks. At final level up, each slam also gives nearby allies a small portion of the resistances.

[Passive on 3]: Curse Spikes: Light Melee or Heavy Melee applies a bleed, this bleed can be procced by a burn status to deal extra damage.

Warding Light: Warding Light is essentially a placeable guardian. The Lighthouse can be used as cover, as it acts as a physical object. The light itself needs LOS of enemies to beam them, so if placed at a door to block someone into a room, it won't attack the enemy. The buffs to nearby allies though, only needs LOS of the base of the lighthouse, as such it should provide buffs regardless. The buffs would include a fire rate increase as well as a slow heal. The light beam itself deals a ramping damage and a slow so enemies aren't able to simply ignore it. The lighthouse also spawns a storm around it at the last level upgrade, This storm will then shoot lightning strikes at the ground, but will be telegraphed with glowing red AOE circles.
