This thread is for conversions of existing monsters to 20th-level 4e critters.

As an unexpected bonus, we have the darfellan in thsi entry.

OCEAN STRIDER
Ocean striders are strange fey creatures that protect the seas and oceans of both the World and the Feywild from would-be despoilers and sailors. These immense fey consider those that would plunder the depths and take their treasures to the land to be reprehensible barbarians.

Ocean striders resemble gigantic humanoids with a strong resemblance to killer whales. They are striking and tend to appear dramatically from the depths, sometimes offering sailors a chance to parlay before destroying their ships for whatever crimes they have committed.

Another, smaller race exists that is clearly closely tied to the ocean striders. Called darfellan, these strange, orca-like humanoids of fey origin are much less powerful than ocean striders, but often accompany them as lackeys.

CRYPT THING
Crypt things are skeletal undead. They are usually encountered sitting or reclined, for they disdain physical combat. The danger a crypt thing presents is rather in the form of its ability to disperse the party widely throughout its lair. A crypt thing can deprive each character of the support and backup of his allies- a potentially lethal circumstance.

However, crypt things are generally not evil. Rather, they usually serve as guardians, dealing with intruders by teleporting them away, and some play riddle games or engage in other contests of wits with adventurers, allowing those that can defeat the crypt thing passage.

VAPORIGHU
Vaporighus are terrible monsters from long-lost astral dominions that exist to waylay travelers and tear them limb from limb, seemingly without reason or real motivation. Though they can sometimes be reasoned with, it is usually only when the other party has a clear upper hand.

A vaporighu looks like a hideous, bloated blob of hairy flesh that waddles along almost comically- until it strikes. Vaporighus drip with corrosive slime and strands of decaying, gangrenous flesh. Small horns top the head of a vaporighu, and it reeks of sulphur and other, fouler things.

If it has three wear points, the weapon is destroyed. If the weapon is magic, it can receive one additional wear point without harm per tier. If the wielder is immune to acid and the attack is melee or close, the weapon is immune to this attack; if the wielder has resist 10 acid or better and the attack is melee or close, the weapon gains a saving throw to avoid gaining a wear point.

Loping Move (move; recharges when the vaporighu loper takes damage): The vaporighu loper shifts 2 and then moves 4.

[Mesh Hong]

Unfaltering (immediate reaction; when first bloodied) Healing: The lammasu paladin spends a healing surge and regains 51 hit points. It gains +2 to saving throws until the end of the encounter or until no longer bloodied.

I think the effect of this power should be looked at again, when first bloodied it can heal 51 HPs and gain a +2 bonus to saves, the healing will probably take it back to an unbloodied state but the duration states "until the end of the encounter or until no longer bloodied".

Are you saying that:

if the creature heals but is still bloodied it only gets the +2 to saves while it continues to be bloodied? (by which you are making an assumption that another creature might heal it)

if the creature heals and this takes it to an unbloodied state it gets the +2 to saves for teh rest of the encounter?

Why not just give it a straight +2 to saves until the end of the encounter?

Oooh, a very good point.

I'll need to rework that- what an obvious flaw, and I totally overlooked it! Thanks for catching it.

 

[the Jester]

Okay, so here's my revised version of the lammasu paladin's unfaltering ability:

The lammasu paladin spends a healing surge and regains 51 hit points. It gains +2 to saving throws until the end of the encounter or until it starts and ends one of its turn without being bloodied.

That way it might last for the rest of the encounter, but if the pcs let up on the paladin for a round or two it could lose its unfaltering ability.

How does that look?

RAGEWALKER
Ragewalkers embody the natural forces of war and combat in the same way that a dryad embodies the heart of its tree. These deadly fey emerge from a landscape torn and twisted by war, and they are nature’s response to the ravages of such battles. The ragewalker exists to perpetuate combat, turning man and beast alike against each other. Insane by the standards of any but the uncaring forces of nature, ragewalkers seek the annihilation of all war through the annihilation of all those capable of making war.

A ragewalkers is covered from head to toe in tight-fitting metal armor made up of pieces scavenged from the battlefields that spawned it. This armor grafts itself to the ragewalker, who is also surrounded by a cloud of circling weapons that lashes out at nearby creatures. Beneath its armor, a ragewalker looks much like an elf or eladrin.

If the triggering attack hits, the ragewalker makes a melee basic attack against the attacker as a free action.

Fey Step (move; encounter) Teleportation: The ragewalker teleports 6.
