Does anyone know the min skill for taming a Young Nightmare?

GM Taming is needed, though you could potentially tame it at less. *Very* unlikely though.

As for giving out free taming skill with an untamable mount, we won't be doing that. There are already some very hard-to-tame mounts out there (Dappled Dream Mare for example) that require more than 100.0 taming skill to raise, so you have to macro on them for a while to tame them.

The best way to raise it is to just keep taming mounts over and over. You can buy some with less than 5 tamers to release and re-tame them, or hunt for them yourself. Or even just tame normal monsters/critters for skillups.

Oh, and I changed your avatar from gore to a fluffy kitten.
