Perhaps I'm playing Dracul wrong, but he seems (as well as Tikki Tokki) a little underpowered comparatively. I think this is mainly because of how slow you gain piety with him. You get two per kill and 5 per health potion convert, and that's all I've found so far, so if there's some other way to gain piety that I don't know about that might be my problem, but here's how I see it.
His first two abilities let you gain piety for losing health and levels. They are useful, especially when fighting the boss when ten health or two levels you weren't going to get anyways can turn into a full heal, but they are bad for other reasons, which I'll explain.
His next ability lets you use 20 piety to get 2 mana. Not useless, of course, but made rather lackluster by Mystera. Sure, for each two mana Mystera grants you create 4% magic resistance on your enemies but you gain piety so much easier with her affording the 40 piety needed to negate that is easier than just getting another 20 with Dracul for another two mana. Still, it's not a bad ability by itself.
The next is life steal. 5 points per 20 piety. Life steal right now heals a straight up fixed amount of damage each attack after damage is dealt. Functionally, it can be thought of as a shield-type item that blocks damage only if an attack would be survivable in the first place, which I think is a nice drawback given that one could theoretically block up around 6x more damage than Taurog's shield if one was insistent on pumping Dracul's lifesteal buff. Plus it allows for weak enemies to be used for lots of healing so it is by no means a weak ability. Still having to survive for it to be useful means weaker first strike based characters are left out in the cold by Dracul and it's just plain useless against some high attack bosses.
After that, we have a 4% resistance buff per 20 piety. Again, this is overshadowed by other gods. It take 80 piety to get to 16% resistance. Taurog does essentially that for 50 and Glowing Guardian does that for 100, but with plus 10 health, 2 mana, 5 base attack, and 100 conversion points. Since for 100 Dracul could give you 16% resistance and plus two mana, Glowing Guardian's ability is just way better overall, especially given how easy it is to get piety with him.
Finally we have a full heal for 20 piety. I think this is overall the best buff he has and there's not too much to say about it. It's good.
Okay, after all that explanation about what he does, let me point out what I think is just so wrong with him: he has absolutely zero synergy with himself.
Glowing Guardian creates piety on every convert. I typically get enlightment around level 4. Once you get that, killing higher level monsters is a breeze, letting you build back up huge piety gains for protection to be used against the boss. Using his abilities naturally enables to get better at earning piety under him, from using Sanctify on low level enemies and Protection and Enlightment on high level ones.
Same thing with Mystera. Her abilities give you more mana which let you cast more spells which lets you get more piety to use her abilities more and...
Taurog too. Kill things, get better at killing things, kill more things.
Dracul doesn't work like that. You can lose 10 health to get more life steal, but then you won't be able to survive the strike needed to use it. Likewise, 4% resistance will never equal 10 lost life unless you're against Gharbad, but then that won't really matter in the first place. The level up ability is a lot better right now, since with it you get more effect from health boosters, more fireball damage, and most importantly you still only need the same amount of experience to level up. However, given that in the freeware, Dracul's extra level meant you had to gain another 5 experience to level than you would have had to before, I'm thinking this is a bug and will be fixed eventually, essentially nerfing that ability.
No matter how you use his abilities, however, you'll never get better at converting health potions, his biggest piety boost.
All in all, Dracul's abilities are both overshadowed by other gods and often times work against each other. Coupled with how slow piety gain is for him he's a chore to worship. So I'm going to finish this off by suggesting a few possible buffs:
1. Life steal can overheal you. This makes it a much more powerful ability and more importantly rewards first strike, which would let Dracul be more useful for rogues, who normally can't give up the health needed to really use his abilities.
2.Dracul's Blood Shield gives 4% physical and magical resistance, as well as a X% dodge ability increase. Four might be too high for this one given how Tikki Tokki has 10% one use dodge buff for 25 piety, though I'm kinda for making that one repeatable as well, though that's a different topic.
3. Rework his piety gain system. Most of his abilities are buffs to your damage resistance one way or the other, through armor, life steal, or full heal. Perhaps a system where some fraction of resisted damage comes back as piety? Toughest problem, I think.
Thank you for reading all of this. Any other ideas about what's right or wrong with Dracul right now?
