As per the title: whenever my Dragon uses his Blast ability (a.k.a. Dragon Fireball), it does no damage. The animation plays, the projectile fires, but the enemies don't flinch and don't take damage.

Does anyone have a clue what might be wrong?

Thanks in advance!

Did you alter you savegame by making dragon learn his attack, but not "expertizing" his dragon skill?

And do you mean you installed MM8 and Greyface's patch on top of it? Did you try without patch, as MM8 already has Greyface's bugfixes in?

I tried it with Naga's & Mercenaries.

I use GoG's version, with Greyface's patch.

Misscliked and screwed my 1st post, so my reply is mirrored now.

No, the Dragon learned its skill naturally. His Fly skills works perfectly, for example.

Greyface is installed on top of MMVIII, since it's a new patch, from a couple of weeks ago.

Seems to have fixed it, thanks!
