D&D 5E (2014) Is it just me or does Tiamat kind of blow in Tyranny of Dragons?

[Chocolategravy]

She is a bit of a handful but doable for a level 20 party. Considering she is CR 30 so shouldn't normally even be fought by a party below level 30, she is pretty under powered. I could see a level 20 party gating her in and kicking her butt for giggles.

Where is the description of how legendary actions work?

In the MM. But in the MM dragon descriptions it says they refresh each round, maybe the stat block in RoT didn't have that. My fault for not grasping the new rules though.

I love that she has 5 legendary resistance/actions. I'd really like to see a full range of legendary monsters, some with just 1 point, others up to 5 like Tiamat, not just 3 like it is throughout MM.

She should have a few Inspirations as well. 6 or 7 (who says that deities cannot have more than one?). That would teach those pesky 20th level guys.

I'd give her max HP for one though but I hate average HP stuff.

I am sure their is som thing someone can do at level 5 to kill her

Rear left toenail.

Shatter that claw and she comes crumbling apart into thousands of multi-colored harmless foot-long garter snakes with mini dragon heads.

Aim for the hollow of the left breast ...

You know that legendary actions refresh at the beginning of every round, right?

That means she can use a breath weapon (on average) 6 times more often than the red in your example.

Edit: Maths is hard.

Not at start of round - but at start of the creature's own turn. A minor, but occasionally important, element.

Inspirations is a better mechanic than the legendary saves. If she (and other legendaries) got a couple of those on a recharge it would help them seem a little less like DM fiat and a little more like the vagaries of battle.
