Alchemichal Reagent question


Rules Questions


So I'm in a mythic campaign, and we are about to face an ancient white dragon who has been really hyped up. I'm playing an exploiter Wizard, and We should be able to catch the dragon after prebuffing. Thing is it will definitely still be a really tough fight. One thing to note is that the GM is definitely using a custom statblock for this creature, so I know that I don't know anything that you couldn't gleam from a skill check. So I'm trying to eek out every little advantage I can get, down to the alchemical reagents for some spells I will use.

My opener will be a swift action Empowered Enervation (Mythic Path Ability), then a Piercing slow (peircing coming from a rod) I'm going to have Mythic Encouraging Heroism on, and great destiny too, and I will use great destiny for spell pen. I know for slow I can use ginsing to get that little extra +1 to spell pen for slow, but I'm really not confident in getting it to fail its save (DC 23) Which is where Enervation comes in. Thing is I want to also use Salt to increase my spell pen, but it seems like that doesn't work, that "effect" does not include spell pen. Is that correct? Is there another alchemical reagent that can help here?

I’d go for spells that target its reflex if I’m going to make it roll saves. On defense, arcane sight and greater dispel could also help in a big way if you’re going in not knowing about it. Grand destiny and myrrh will apply to those dispel checks which is pretty awesome.


An increase to caster level for "purposes of effects" includes caster level checks, which includes caster level checks vs spell resistance.

If you want more reagents, there is Nethys's dagger and dweomer's essence. You can also use a Numerology Cylinder or even the Sure Casting spell if you really need to.

I assume you are already taking into account that Mythic Heroism also improves caster level checks?


Use Heighten Spell in you highest level spell slot to further increase the DC of the save. You can obviously cast at least 6th level spells so that would increase the DC by 3.

I am assuming you also took the exploit potent magic to raise the DC by 2.


It would be better to use Persistent Spell.


Hey guys thanks for the answers. Unfortunately I don't know heighten spell, or persistent spell, and I don't think I will be able to get my hands on a persistent spell rod, but I'll give it a shot, I can use lesser, making it easier.

Nethy's dagger, dweomer essence, and numerology cylinder are really what I've been looking for, so thanks!

I know I should target reflex, but I really, really need the effect of slow, unfortunately. We have some intel on the dragon. A group of legendary dragon hunters went aftter it. We are lvl 11 mythic 2, We suspect these hunters were lvl 13-16 and not mythic. It was doing flybys and serious control spells, and the result was that it one hit killed each of the hunters, including a barbarian. I need to prevent flybys. We are already certain pretty much that maybe our barbarian can take one hit, and anyone else will die one shot, and it's my job to prevent the flybys, and keep it on the ground. So slow. Unfortunately it will still one hit kill anyone it attacks, but well, what can you do?

Also, do negative levels reduce spell resistance?

As the rules read, no. It's not one of the things that is reduced by energy drain. The universal monster rule on SR doesn't help you either; it just says the monster has an SR, not that it's based on anything.

The Dragon Rules say that SR is based on CR. Which might make for a reasonable argument that the SR should be reduced by energy drain. The problem is that energy drain doesn't directly affect CR either. The target doesn't lose absolutely everything they got from the higher levels. Spellcasters, for example, don't lose spell slots or prepared spells. So you'd have to come to agreement about what the new CR "should" be.

As a GM I would probably say "no" to reducing the SR. But I'd be OK with a GM who reduces it by half the negative levels (or even 3/4 or all).

Note that there are some cases in which SR is explicitly based on level. The dwarf "Magic Resistant" alternate racial trait, for example. It's just that dragon SR is not one of them.

Edit: Just remembered that there is a table in Bestiary 1 (page 291) that lists the average HD for a given CR for each creature type. In theory you could use that to work backwards ("It lost X HD, which would move it from the CR Y column to the CR Z column") and determine new SR from that. The problem is that is the average. A CR 15 dragon (such as an ancient white dragon) would have 18 HD according to the table. In actuality an ancient white dragon has 21 HD. It's another tool if your GM is willing to work with you, but I personally would stick with "no reduction" for simplicity's sake.

How long after pre-buffing do you expect to enter combat? There are some short duration spells that could help like Cleromancy or Calculated Luck.

Harrowing is a much longer duration luck bonus, but you really need to draw a crown that matches your alignment. This is one of those times that Fleeting Spell is really useful. Keep trying until you get the result you want. A rod of Fleeting Spell hasn't been published but that doesn't mean one can't exist (check with your GM).


Sure Casting:D1 is +5 vs SR.
