Leyline Arcana: Practical Magicka (5e Sourcebook)
From D&D Wiki
A D&D magic system for engineering-inclined minds!
HOMEBREW DISCLAIMER: This sourcebook is a HEAVY Work in Progress, full of balance issues and game-breaking exploits. I recommend not using this sourcebook unless you're making a campaign to playtest the mechanics.
I need to get familiar with MediaWiki's MarkDown and editor before I can contribute anything meaningful to this page, but I just wanted to initialize it for now so it will be here once I figure things out.
