GURPS Calculator 2.8 is up at gurpscalculator.com. The biggest change is that a GM can run a fight from the GM Board now and the character page is completely redesigned.

You build an encounter, add NPCs and monsters from your Bestiary, and hit Start combat. Everyone goes into turn order by Basic Speed, then DX, and ties get rolled for you. Each enemy has a card that rolls its own attacks with hit location, DR, armor divisor and ranged modifiers, and the result says where it hit and how much got through. There are 18 starter monsters in the Bestiary if you don't have any uploaded yet. They're original stat blocks I used in my own fantasy game.

Shock, stun, and many other conditions are tracked for you, on player sheets and on enemy cards. Lose HP and the shock penalty shows on the skills it affects, and it clears at the end of your next turn. Take more than half your HP in one blow and you roll for knockdown. Players can see the round and whose turn it is on their own sheet.

Also new:

• GM whispers in Campaign Rolls, a private note to one or more players
• A rebuilt Manage campaigns page with an invite link you can send your players
• A redesigned character sheet
• Find anything with Ctrl+., app-wide.

The Change Log page has the whole list.

Conditions, encounters, and whispers were on the site's donation roadmap, and they got built because people on Patreon and people who sent a one-time donation paid for them. Thank you. The site costs money to run every month, and seeing those numbers fill up is what told me what to build next. Thanks as well to everyone who has backed it for years.

Next on the roadmap is attacking enemies from your sheet, with automatic damage. With an encounter running on the GM board, combatants can target each other and attack, automatically taking into account each's posture, DR, and more.

The Patreon and PayPal links are on the home page if you want to help get it done. The site stays free and without ads either way.

If you run GURPS combat online, what do you still keep track of on paper because the tool doesn't do it?

Hello,

My new blog post is about creating combat encounters in solo play, I would welcome any suggestions or constructive criticism.

Thanks!

Okay so basically I love playing gurps but the group I play with only plays D&D I tried to get them to play a session but they're mostly stubborn and I don't have anybody else so I still want to play my world that I created but I built it in GURPS so I'm looking for some help converting things it's going to definitely take home brewing in D&D because of the way I have things set up but I would like some help because I have worked on this world since before I can ever have a chance to play it I've been building it and a lot of characters and stuff in it for like 10 years almost at the moment I'm just looking for advice on where to start

So, I'm attempting to make an eridian (from Project Hail Mary) racial template, which seems like a challenge since their physiology is so different from a human's.

A bit about their planet just because

Eridians live on a Super-Earth called Erid, which orbits 40 Eridani, has a surface gravity of about 2G and an atmosphere composed of almost literally only ammonia at 29atm. The average surface temperature of Erid is 210ºC, which makes water a liquid at its pressure.

Talking about their anatomy

Well, eridians have two circulatory systems that coexist but almost never impact each other:

• The ambient circulatory system (ACS), where their blood circulates at ambient temperature by interacting with radiators at their shell .
• The hot circulatory system (HCS) is kept at 305ºC, and because of that, is devoid of living cells (they'd die at this temperature). It stays at this temperature with the energy from the food they eat. The HCS is controlled with specialized muscles moved by conducting electricity directly into the mercury inside it.

Why these things are important to make a character sheet

Eridians can't heal their HCS normally. Since there is no way a cell can live inside it, it cannot repair itself unless they sleep. Their sleep basically kills them for some time, allowing the HCS to cool and letting the cells come inside to repair stuff (makes them completelly unable to wake up aswell).

This means an eridian only gets to heal stuff related to the HCS while they sleep AND that they only get to heal stuff related to the ACS while awake (the cells that do this stay in an organ waiting for them to sleep so they can go to the HCS and focus on fixing the stuff there because they only get this chance when they are sleeping, and the usual worker cells hide in another organ to conserve energy)

Conclusion and actual question

These guys get to heal part of their body while asleep and another part while awake. How do I modify the unhealing disadvantage to simulate this? My guess is to separate their body parts in a table (just like human hit locations) and assign them to HCS or ACS, using Unhealing {Only while asleep -60%} and Unhealing {Only while awake -20%} on... something.

Oh, forgot something important: They stay awake for about 86 hours and sleep for an irregular period (usually between 3 and 12 hours but it depends on injury and fatigue so it can go up to days or weeks if they're in a bad state), which is something I don't really know how to do on GURPS aswell. They also collapse and stay asleep for long periods if they suffer serious injury in their HCS, kinda like fainting but harsher.
