Siphon Flask Monster Attribute

Playing Pathfinder for first time and around delve depth 225 started to run into a mod "siphons flask charges"

I mean GGG why is this a thing? I don't understand why a single monster mod negates an entire class.

Is there a counter to this mod? Should pathfinder just not delve?

Is that the design principle? Every class needs a hard counter because characters need to die? What in the heck.

ya'll have a team of people sitting around a table finding ways to make this game as painful as possible?

I would like to respectfully suggest the "siphons flask charge" mod on monsters have a visual cue like mana siphoner.

There is so much crap on the screen no player should be expected to mouse over a monster.

I think the visual is particularly important as it completely bricks an entire ascendancy. I get that you want people to pay attention but at what cost? I think that mod is cheesy so at least give us some agency to avoid it.

Right now you don't know it happened until you're dead -- particularly in delve.

Drought Bringer: This mod is fundamentally a reasonable one, but the area of effect is too large, rendering it unreasonable. As implemented, its counter relies upon RNG-based absence rather than player skill to defeat it when RNG has caused its presence (in an instance with somewhat tight quarters). Referring to the OP's example of Delve, the character might be able to successfully flee a Rare creature that has the mod during the mine crawler's movement phase, but the character might be doomed if said creature is present after the mine crawler has nearly or completely reached its destination.

Were the area of effect sufficiently smaller, it would be a more feasible task to counter the effect with skilled movement and positioning, even in an instance with tight quarters.

On a side note, this mod (as it exists), is another nudge pushing Mageblood into the realm of overpowered gear. Mageblood is already extremely potent, without this mod showcasing the contrast between dependency upon flask charges and non-dependency, in flask-effect dependent builds. Its provision of immunity to the dreadful effects of this mod (for most of its flask-effect-dependent users, not all, granted), is yet another cherry on top. On the other hand, it doesn't take more than casual study of Mageblood to identify it as a creation lacking in nuance and respect for the notion of balanced items (regardless of their rarity) within this complex game structure, and as a design-example of incapacity (or unwillingness) to temper extreme power with a fitting price in the form of drawbacks. Rare or not, it is the equivalent of a cheat code.
