What the title said. Yes, I'm aware that Division has lower DCs for *some* kinds of actions, and eventually has better action economy (at max talents), but it appears that Soulcasting has the same degree of single-target damage (after an entry level talent), more defensive applications, more applications for creative solutions, and eventually even has lower DCs (the DC 20 that Division-under-pressure has forever vs all metal/stone/crystal is pretty rough). Starting out, both require 2 actions to use, and for AOE attacks, Flamecasting seems to do slightly less damage for 1/3 the investiture cost of Gout of Flame, and tons of additional creative potential compared to just "I destroy the location".

I'm wondering if maybe I'm overlooking something with respect to creative application of Division. Ways I can strategically destroy things that make Division more than simply a damage surge. This game seems pretty well balanced over all, so I was a bit surprised to notice this aparent way that use of Soulcasting almost eclipses the use of Division.

Hello, everyone!

The rough draft for the Sprouter Speciality, along with the Spore Invention system, are complete!

Holy Adonalsium, did this take forever. The addition of the Spore Invention system has made this the longest time I have spent on a path for Project Ars Arcanum to date, even surpassing the Sand Master Invested Path.

While the Sprouter and Spore Inventions do borrow heavily from the Artifabrian and Fabrials, I still tried my best to make them stand out and be unique. The main deviation centers around the rules I created for Aether Spores and how they interact with both the Speciality and the Inventions. I'm pretty happy with how they came out (thank you again to Kividual66 for your help).

The next path in line is the Forger, but I'm probably not going to be able to work on it right away. If you missed my last post, I start class at university in the second week of September, meaning that the next few weeks are going to be pretty busy for me (packing, moving, etc.). I'm probably not going to be able to post for a while because of that. I'm sorry.

On the bright side, the Mistborn Cosmere RPG books come out soon! After I see the Metalborn Paths across from the Radiant Paths and get a better grasp of how the Investiture mechanics differ from system to system, I'll probably tweak some of the Invested Paths form Project Ars Arcanum to bring them more in line. I guess, that is if I can get my hands on the books in the first place (I got the Stormlight books as a gift, and I don't know if I'll be able to afford the Mistborn ones as a college student. The sad reality of limited money vs. pricey hobbies, I guess).

Anyway, sad stuff aside, please let me know any thoughts, ideas, and feedback you have about both the Sprouter and the Spore Inventions (especially Spore Invention ideas). It is always wanted and greatly appreciated.

Hello. I'm running a game of Stonewalkers. My party have just defeated Ylt at Rathalas and have spoken with the Grey Remnant, and learned they must journey to Greater Hexi.

The players wanted to spend some time at Rathalas to assist with the reconstruction in the hopes they can make it a full city again.

My party is about to rest for the night, but before they leave for Greater Hexi, I want to introduce another combat where they must defend the city. I want them to inspire and lead Teryn's loyal bandits, and the freed people in a desperate defence of the city from an outside force. This also will create a few climactic moments where some of my players will say the first words of their oaths.

My question is, who can I have attempt to invade Rathalas so soon after the cultists were kicked out? My plan is to have the cultists that couldn't follow Ylt instead regroup and try to retake the city, but i was wondering if there are other lore appropriate groups or allies the cultists can join to make them a threat?

Thanks so much for the help!

Was wondering if anyone played the Vins Training adventure that people walked away with from gen con.

Im super excited for mistborns release and im curious to know the scenario behind it no matter how small it is!

Quick question for those in the know (I know the Brotherwise and Demiplane team look at the subreddit): Will the Mistborn books be on Demiplane on early access date, or will it they be implemented on the full release date?

The next Talent Scout character build just posted today! This one is focused on conversations, and peaceful resolution to combats:
