The Sorceror Toolkit

A growing suite of tools for Mortal Online 2 — built for the community, free for everyone.

Siege Planner

Pick the structures you'll attack and get the exact boulders, stone, mangonels and estimated time to destroy them — using real structure HP and in-game boulder damage, with the supply-storehouse buff factored in.

Building Calculator

40+ structures across houses, walls, vendors, defense & siege — with accurate cumulative tier costs. Stack any combination, see totals live.

Upkeep Tracker

Track upkeep for all your houses, keeps and structures. Enter the time left and get a clear warning — on the home page and after login — before any of them expire. 20 gold = 60 days.

Ore Extraction & Refining

Extraction yields with machine, catalyst and Clade + Mastery bonuses — plus a reverse Refining calculator: tell it how much Tungsteel, Steel or Cronite you want and it breaks the whole chain down to the raw materials.

Alchemy & Botany

Extraction yields for Alchemy, Herbalism & Milling. Compare presses, grinders and herbologiums, with the 5% Herbalism Clade bonus built in.

Butchery Reference

Carcass yields for 170+ creatures & fish. Search by animal or material, filter by zoology root, scale to your haul size, and toggle Alvarin Clade (+10%) and Mastery (+6%) bonuses.

Cooking

Every ingredient and its properties, the recipe ratios for each dish, and 900+ tested recipes sorted into quality tiers — sort by health, stamina, mana and more to find the best food.

Material Attributes

Consumable stats for 370+ materials — health, stamina, mana, healing & poison. Sort any column, filter by type, find the best food and reagents.

Skill, Ability & Scroll Books

450+ skill books, combat abilities and magic scrolls — where to buy them, prices, vendors, mob drops and scribing ranges, organized by profession, weapon type and magic school.

My Character

Build your skill profile once, then every reference page highlights in gold what you can already use — what you can butcher, scribe and craft — and dims what you can't yet.

Armor Workbench NEW · WIP

Craft a full set — pick set, core and padding material, tune material use — and read the exact per-piece blunt, pierce and slash defence, weight and durability. Save builds straight to your character. Work in progress — more sets & materials being measured.

Guild Ranks

The full permission matrix for all 10 guild ranks, from Initiate to Guild Master — see exactly what each rank can do, in a table or per-rank detail.

Save & Resume

A free account lets you save unlimited builds and your character profile. Plan your guild's village across multiple sessions — everything stays with you.

Frequently Asked Questions

Everything you might want to know before diving in.

Yes. Every tool on MO2 Builder is completely free for the Mortal Online 2 community — building and siege calculators, refining, upkeep tracking, butchery and reference databases. There are no ads.
No — every calculator and database works fully without signing in. You can plan a whole siege, price out a build, work out refining or browse any reference without ever making an account. An account is completely optional and unlocks one thing: saving and loading your work. Logged in, you can save named presets — building plans, siege setups, refining lists, cooking and butchery plans — and load them again later from any device, and your character profile and upkeep timers are kept too. We know the MO2 community is rightly cautious, so to be clear: any real email works (it’s only used so you can reset your password), it’s never connected to your game account, Steam or character in any way, your password is stored encrypted so no one — including us — can read it, and we never send marketing or spam. That’s the whole deal, no catch.
Yes, with a free account. Tools like the building calculator, siege planner, ore refining, cooking and butchery let you save named presets and load them back whenever you want, on any device. Without an account everything still works — you just can’t save between visits, so the save buttons will ask you to sign in first. Upkeep tracking and your character profile also save to your account so your structures and skills are always there when you come back.
Most MO2 tools cover one thing — MO2 Builder pulls the whole crafting-and-warfare side of the game into one place, and includes several tools nothing else offers. The siege planner takes the structures you plan to attack and works out the exact boulders, stone, mangonels, build time and gold, using real structure HP and the in-game boulder-damage formula, even accounting for defence dropping as a structure is destroyed. The reverse-refining calculator runs backwards: tell it how much Tungsteel, Steel or Cronite you want and it breaks the whole chain down to the raw ore and catalysts. The upkeep tracker groups your structures by location, warns you before anything expires, and shows the exact gold to top everything to 60 days. On top of that you get a full building calculator (40+ structures with cumulative tier costs), ore, alchemy and cooking yield calculators with clade and mastery bonuses built in, and searchable databases for butchery, materials, skill & ability books, magic scrolls and guild ranks — plus a personal character profile that highlights exactly what you can use. It’s all free, with no ads.
Structure costs and HP come from compiled community data, and formulas like boulder damage are based on confirmed in-game values. Siege figures are planning estimates — real fights have factors a tool can’t predict — and we update data as the game and community findings change.
Yes. MO2 Builder works in any modern browser on phone, tablet or desktop, and the layout adapts to your screen.
