Not sure what you are trying against him, but he has 0% immunity to Fire and Magical Fire. Only Red Dragons have that immunity. Dasypus is partially immune to Cold and fully immune to Electricity... hence all the Lightning Traps.
What I based this off of was the fact that when Melf's Minute Meteors get used against him I see messages to the effect of "target was immune to damage...." things. Plus when I tried to use dragons breath on him in my first two tries it never did any damage. Comet & Abi always did though so I stuck with those later to great effect.
Right now he has two Time Stop scrolls. Do you think two is too much? The way I adjusted the LOCALS, he doesnt use them back-to-back, but rather waits a bit before using the second. He also carries a scroll of Restoration... should you level drain him too much.
I never let him get that second one off. I was letting him have the first, mostly because I didn't understand how the healing was scripted. I just noticed that more times than not he was 100% healed after a timestop. So I always made sure I did minor damage to get him to waste some healing in that first timestop & THEN I would really go to town on him.
Lithify: He has virtually no limit to use of this ability, but there are alot of other things higher in the script that take priority. Twice is good... but I have had him use it on my party a dozen times. You can protect yourself with Protection from Petrification wizard spell.
I realize that, but I also think it's a bit cheezy to specially prep a party based on foreknowledge. Sure *I* know exactly what is coming sometimes & could protect my party, but what kind of roleplaying is that? I have to admit that I do occasionally special prep for battles, but I avoid it when possible. I feel much better about walking in cold with no prep or summons and wacking Firkraag & his pet mage than I if I summon a lot of monsters & then cast cloudkill offscreen or something. Of course "real men" sometimes take real beatings after trying things this way.
Both RP wise & the first time folks fight Dasy they will have no clue & the Lithify will be a big suprise. This is one heck of a powerful attack & the one that more often than not is what has gotten most of my party members killed. In my first few fights where the Djinni was locking things up Dasy usually killed Anomen in melee, and both Keldorn & Mazzy with Lithify. My mages would then fight on.
Since then I've started using more summons as buffers. The Clay Golem from the book, Mord's Swords, and a Diva. These usually distract him and have been very useful for keeping party members alive. Does Dasypus try to use Lithify when he is in melee?
Also given the lack of rest areas how many players will have this spell memorized by their mages without foreknowledge? Not many I bet.
I am disappointed that more people havent reported him using backstab. He wont get the opportunity often, when he it hits... its nasty. He only does Quintuple damage, but that is usually enough to kill Sarevok or Keldorn outright.
True Seeing. I use it as soon as he goes invisible. I think that this would make it harder on him. What would really be murder is if he did this during timestop, but thank goodness true seeing works there too.
Cuv, could you clear something up for me? Is Dasypus a living dragon or a draco-lich?
Also one last thing I've forgotten to note previously. For some reason my Chain Contingency spells set to go off "When Foe Spotted" don't go off when we first enter the room & see a hostile Dasy. Usually they get triggered after he goes invisible & reappears the first time.
