Boss Forge

Pricing with a receipt

Credits you can count before the forge starts.

GLM 5.3 Flash is the public text engine. Every request has a fixed credit price, images stay separate, and the model comparison below uses published provider rates rather than promotional shorthand.

Open the NPC forge

Approximate monthly capacity

Fifteen complex illustrated NPCs start at $5.99.

Counts use a complex GLM Flash text block plus one token. Extensive lore, spellcasting, ability alternatives, and additional images reduce the total.

Text model comparison

Toggle the model, not the fine print.

Public GLM requests deduct the listed credits. Gemini is owner-only for testing: the panel shows the server-calculated standard-account rate, while the owner's unlimited entitlement means an actual owner test deducts 0.

Image variants: one costs 8 credits, two cost 16, and three cost 24 credits total. A monster can have at most three generated variants. Minify for Roll20 is a separate +1-credit request for each image you choose to minify.

Mythic and Epic pricing: these optional modes require Legendary Actions. Their generated actions also count toward the stat-block complexity tier, and the forge displays the complete additive price before generation. The complex tier has a 7-credit base plus 1 credit per started block of 8 actions above 15, so a 16-action forge costs at least 8 text credits. The surcharges cover the extra transformation, carryover, action-pool, and item-generation passes; they are not represented as measured provider cost.

Why 15x for Gemini text: the fixed comparison follows the non-promotional output-rate ratio, $7.50 / $0.50. Google's temporary 2026 introductory rate is deliberately excluded so customer pricing does not jump on January 1, 2027. Images are not multiplied because this toggle controls text generation only.

Roll20 Tools · Alpha Edition

Chrome-extension import without requiring Roll20 Pro.

The editor converter targets the Roll20 2014 5e NPC sheet. “Minify for Roll20” sends the generated token through a third-party optimizer, stores the resulting WebP in the same Boss Forge cloud bucket, and keeps it under 30 KB so it does not consume the user's Roll20 upload storage.

Ability alternatives

One request at a time, up to three temporary choices.

Generate one

Boss Forge does not automatically spend credits on three abilities. Each click creates one paid candidate.

Keep up to three

The temporary inventory lets the GM compare candidates without changing the live monster.

Guide exact mechanics

Dice, modifiers, save DCs, ranges, and damage types supplied in guidance are validated against the description and Foundry automation.

Finalize before export: apply the chosen ability, discard temporary alternatives, then use Finalize Monster. Automatic candidates must differ mechanically and descriptively while staying on theme.

Checkout and rules provenance

Verified identity in. Pinned SRD spells out.

Verified checkout

A Firebase-verified account is required before Stripe Checkout begins. The selected product survives the sign-in handoff.

Discount-ready

Checkout enables promotion codes and uses Stripe API version 2026-08-26.dahlia. Stripe supports valid coupons up to 100%; the API version is pinned for response stability, not marketed as the source of discount support.

SRD 5.2 class spells

Class spell hydration accepts only the pinned dnd5e spells24 catalog labeled SRD 5.2 and CC-BY-4.0. Other source metadata is rejected.
