Don’t use any homebrew and just run open legend as is.
Your still new.
Just like what @VanGo said. When you are new, not just to Open Legend, any new system in general. You shouldn’t already try tinkering around with the mechanics.
It would be like trying to create your own custom recipe after only learning how to cook.
Speaking from experience here from when I first started Open Legend I made a whole bunch of stupid rules that I regret and continue to pop up in my games and annoy me to this day. And also the posts I made in the community that I wish just stop existing too lol.
Everything you want to accomplish can be done with fluff and flavor and proper uhh… GMing and wording (crackers I forget words!)
That’s what Open Legend is and how it should be GM’d. At least I think.
If you want players to have the sense of survival you want, just narrate it as such.
“As your travel across the vast gerudo desert in search of the fabled Arbiters Grounds dungeon, days pass and turn to weeks and your resources dwindle. Everyone, roll for Fortitude.”
React to how they respond if they refuse to roll, maybe one claims they have a perk or feat that could help, hear them out and call out a ruling you deem fair and okay. OL is all about making temporary rulings that only lasts that session on the fly because the GM’s word is final, the GM is always the king in the kings game.
They have the vagabond perk? Let them use it. They wanna look around in the vast desert for food with a Perception check instead? Let them!
Whatever you believe will be fair and fun for all!
Mechanics and rules get in the way of storytelling, instead of using mechanics, just tell them how they should be feeling.
When someone fails to cast their spell, tell them it’s because they ran out of mana and now they can’t use that spell anymore until 3 rounds or after combat ends.
If the fighter fails their shot, tell them they hit but that was the last their weapon could handle and so it breaks. Or that they miss entirely because they are out of stamina, making both them and their target either choose to
- take the minimum 3 points of damage
- inflict a bane of PL 3 or less
- or move 10’ without provoking any attacks of opportunity
If your like me and you really just like conveying and encouraging everything using rules, then I posted this thing about resource management which adds a durability system and harder hit point management
