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.

Demongate Colossus

Creature 14 (unique) — construct

Pre-Remaster content. May include legacy alignment.

The enigmatic and strange radiant wardens were constructed thousands of years ago to protect observatories and scholars against the incursion of alien aggressors from the Dominion of the Black. Over time, their roles as guardians expanded to include watching over any region where the laws of time and space have worn thin, particularly near portals and permanent gates between planets, planes, or dimensions. Named for both the radial nature of the concentric rings that make up their bodies as wel

Abilities

Abyssal Link — The Demongate Colossus is built around a seething, churning mass of Abyssal energy that looks like a sphere of electrified red mist encompassing a single floating harrow card at its center—The Survivor. The Abyssal link is obscured until the Demongate Colossus is reduced to fewer than 120 Hit Points, at which point glimpses of it become visible through tears and holes in its leathery "flesh." The potent magic drawn from this card, combined with the radiant warden's gatewarper aura, is what allowed the Prince of Wolves to invade Harrow Court. Once the Abyssal link is revealed, a character can attempt to counter the Abyssal link with a Dispel Magic (7th rank; counteract DC 34), or can attempt to Steal the card with a DC 35 Thievery (master) check (on a failure, a thief attempting to Steal the card takes 5d10 spirit plus 5d10 spirit{5d10 chaotic and 5d10 evil} damage—this damage is doubled on a critical failure). Either success causes a link collapse.

Gatewarper Aura (aura, occult) — 60 feet. A creature that uses a teleportation ability within the aura's emanation or enters the emanation via a teleportation ability must succeed at a DC 31 Fortitude save or become Drained 1 (Drained 2 on a critical failure) as its body warps and distorts painfully, and have its destination changed to a point of the radiant warden's choosing within the emanation.

Link Collapse — If the Demongate Colossus is destroyed or its belly portal is deactivated, demons that used the colossus's portal within a 40-foot emanation take 7d10 spirit damage (DC 30 Fortitude save). A creature that takes full or double damage is Enfeebled 2 for 1 minute. If the Demongate Colossus is still active when it suffers a link collapse, it becomes Stunned 3 and loses its gatewarper aura.

Corrupted Radiant Blast (evil, force, occult) — The Demongate Colossus releases a 50-foot cone of crimson energy that deals 4d12 force plus 4d12 spirit{4d12 force damage and 4d12 spirit damage} (DC 34 Reflex save). The Demongate Colossus can't use Corrupted Radiant Blast again for 1d4 rounds.

Corrupted Radiant Blow (evil) — When a non-evil creature is hit by the Demongate Colossus's hammer Strike, a red flash of Abyssal energy attempts to infuse the target with evil. The creature must attempt a DC 34 Will save; on a failure, the creature can't use any teleportation effects for 1 minute. On a critical failure, the creature is also Enfeebled 2.
