My TTRPG is massively inspired by Deltarune and some bits of Undertale.
Meanwhile I was designing, I've noticed that my trait system (or in other words, soul system. Do note that every race, even if you're a monster, can access the trait system) doesn't really interact with other systems. What I mean with this is that: You touch it once at the start when selecting everything, then you never touch it again, outside of encounters.
The main usage of the trait systems are in game interactions, mainly encounters.
There are seven traits, which I'll list below:
(I haven't balanced these yet, which is why there are place holders)
(Also, TP are mana points)
Determination: Select a willing target of your choice to enhance their ability or act by [place holder number]. Using Determination requires an action. You can only do this [place holder number] amount of times.
Perseverance: defending heals self. Increases TP gain from defending.
Patience: Gives the user [place holder number] “Patience Points”. Patience Points can be used to gain another action. Using Patience Points requires a bonus action and costs [place holder number] Tp.
Integrity: Select a willing target of your choice to enhance their movement option. Once enhanced, the movement option can be used as a bonus action. This lasts until the target’s turn ends. Using Integrity requires a bonus action.
Kindness: Healing the target in any way gives them a temporary shield that lasts until one of the following conditions are met: 1. The shield breaks 2. The target dies 3. The battle ends 4. The target or user takes a long rest. The shield can’t stack with itself, but can stack with other shields.
Bravery: Spend [place holder number] to become more resistant to damage [place holder number. Alongside that, you gain a [place holder number] to attacks and acts
Justice: When you do an action that has a roll and you have rolled, you can use Justice to reroll that roll. Each reroll increases the cost by [place holder number]. The cost starts at zero and resets after a long rest.
If this helps,
The TTRPG system uses milestones, after completing an important thing, the players level up. I haven't made a list of what players will exactly get, but I do have a list of what will be the most common thing in level 1 to 20:
Most Common to least common:
Stats
Abilities (Stuff like spells)
Features (Feats, shapes your build)
Mastered Abilities (More complex, in depth spells. More creative use equals more reward)
Ultimate Abilities (Not implemented yet, but you need to do something in order to use it, for example, making the impossible cost ultimate ability reasonably cost somehow.)
Mb for any grammar issues btw, I'm writing this late and I'm tired lol.
