Can I run Pathfinder 2e without Foundry VTT?

Yes. PathfinderGM is a lightweight browser-based GM dashboard — no modules to install, no server to host. It covers encounter building, initiative and condition tracking, and session prep, and complements an in-person table or any VTT you already use for maps.

Is this an online GM screen for PF2E?

Yes — one screen with your combat tracker, encounter builder, bestiary lookups, campaign notes, and the Golarion calendar side by side.

Does it use the Pathfinder 2e Remaster rules?

Yes. Conditions, creature stat blocks, and vocabulary follow the PF2E Remaster as published, sourced from official bestiary data under the Paizo Community Use Policy and ORC license.

Is PathfinderGM free to use?

Core GM tools — encounter builder, combat tracker, campaign vault, and calendar — are free. AI-powered generation uses a monthly credit allowance with optional top-ups.

Tarn Linnorm

Creature 20 (uncommon) — acid, amphibious, dragon

Although more powerful linnorms exist, the multi-headed tarn linnorm can wreak an awe-inspiring amount of devastation.

Curse of Death (curse, death, primal) — When a creature slays the tarn linnorm, it must succeed at a DC 46 Will save or it can no longer recover Hit Points via any means, such as healing spells, the Medicine skill, or natural healing from rest. This has an unlimited duration.

Constrict — 3d6+18 bludgeoning, DC 44 Fortitude Constrict

Corrosive Breath (acid, poison, primal) — The tarn linnorm can expel either a 120-foot line or a 60-foot cone of acid, dealing 20d6 acid damage to creatures within the area (DC 44 Reflex save). The linnorm can't use Corrosive Breath or Double Breath again for 1d4 rounds. The acid creates toxic fumes. At the beginning of the linnorm's next turn, those who failed the breath weapon's Reflex save must succeed at a DC 42 Fortitude or gain Sickened 4 from the poisonous fumes.

Double Bite — The tarn linnorm Strides and then makes a jaws Strike with each of their heads, each against a different target. Both attacks count toward the tarn linnorm's multiple attack penalty, but the multiple attack penalty doesn't increase until after the tarn linnorm makes all of these attacks.

Double Breath — The tarn linnorm uses Corrosive Breath twice. A creature attempts only one save and can take damage only once. The linnorm can't use Corrosive Breath or Double Breath again for 2d4 rounds.
