This is true, combat in HARP is a totally different pace. And spellcasting is a totally different animal -- it'll take you several levels before you can reliably throw out a low-level spell with no prep time.
The good news is, if you meet certain conditions you don't have to make a skill check to cast a spell -- there's a whopping 2% chance for a non-attack spell to fail regardless, but you don't risk failing just by rolling a middling result. For Essence casting, these are your conditions:
- The spell is not higher level than you
- It's an Essence spell that isn't from another base list
- It's not cast as a snap action (unless it's instantaneous)
- You haven't used more than 25% of your Power Points
- You've prepared the spell long enough — 2 rounds if the spell's level is within 2 of yours, or 1 round if it's within 5 levels
- You have a hand free
- You're speaking the spell's key words in at least a whisper
- You're not wearing armor or a helmet
- You're carrying less than ~50 pounds of living organic material (so no carrying people)
- You're carrying less than ~10 pounds on nonliving organic material
- You're carrying less than ~5 pounds of inorganic material
Essence-users in RM are assumed to be traveling
really light. It's like the classic "D&D mage not wearing armor" trope, but taken seriously. They explain that too much stuff on your person interferes with your ability to manipulate the world's energies, and inorganic stuff like metal and stone really tamp it down.
