Thanks for the feedback!

Has anyone read the Unearthed Arcana for bastions? Is it good?

Make this a level 15 ability for fighters and then emigrate so that the caster inquisition won‘t crucify you for doing it

Rules option for DnD 5E, specifically for legendary and mythical monsters that tend to be the ones with the most HP:

'Attacks from legendary or mythical monsters hit automatically if they require an attack roll and the effects of the attack would not give the target a condition. Legendary resistances of monsters can only be used against effects that can be assigned to the spell schools abjuration, illusion, transformation or enchantment. Otherwise, monsters can still use their Legendary Resistance to pass saving throws against any effect that would give the monster one or more conditions. In case of doubt, the DM decides. After a monster has used Legendary Resistance, its movement rate is halved until the end of its next turn. The damage caused by the monster’s attacks that require attack rolls is also halved until the end of the monster’s next turn after using Legendary Resistance.

(These rules can ensure that battles are both shorter and more exciting due to the higher damage dealt by both sides. The battles also become more dangerous, making PCs think twice about taking the risk. Creativity is encouraged when considering alternative strategies for conflict resolution. Both ensure that there will be fewer battles overall, which remain the most time-consuming scenes in the game. The increased risk also makes combat itself more creative when searching for ways to damage the enemy or use the environment for a tactical advantage. It also encourages the player characters to improve their supply of healing options, e.g. through the help of NPCs that can cast healing spells.)’

Scribbled together based on this post and its comments as well as some additional ideas I’ve had.

EDIT: Fixed something that got lost in automatic translation.

Interesting, I had the opposite impression regarding the number of dragons. RoT was part of a longer campaign that is still going on, and I always find myself struggling to put another dragon into the game because we already had so many of them, lol.

Overall I loved our time with RoT, picking only some of the cooler given missions and substituting the others with some stuff I had written up myself. So they got to fight a beholder (Xanathar) in its natural environment (Waterdeep) when they had an appropriate level to make the encounter a challenge. Also giving them the chance to obtain the White Wyrmspeaker Mask that had found its way to Xanathar‘s Guild.

Sadly, the module offered no possibility to interact with both Severin and the possible ally faction of giants before the final fight. Solution: Diplomatic showdown to convince a cloud giant of their respective cause. Along with a full-grown battle in the dorms.

Mammon saving the PCs‘ asses from a green dragon following a pact made in a swamp cleared for refugees; the Black Wyrmspeaker as a double-agent who tried to overtake the Cult… God, I loved those ten months. I even got to use the labyrinth from Xonthal‘s Tower at a later point in the campaign because it didn‘t go with our very own version of RoT.
