Mini-6 Marked & Eruption

I'm fluent in d20 rules. I can do that off the top of my head. D6 kinda depends on which version and I've never really got married to any version of D6 (except for Star Wars back in the day). If I run a game today I'd just use Mini-6. It's easy, the core rules are limited and free, and I can add to it on the fly fairly easily. There are few weak spots in the rules, but that is typical for any minimalist system.

BTW, Link here: Mini 6

So, how does marked and eruption work in Mini-6?

A baseline, normal, non-marked human will usually only get 8d for attributes and only 4d for skills. Marked get 12d for attributes and 7d for skills. Marked get access to perks, very few unmarked will ever have a perk and never an esoteric perk. Marked can use Hero Points, unmarked never do.

As you gain character points, you track the total the character has earned. Every time the character earns 10 character points, roll a percentile die (d100). The odds of eruption are equal to your total character points. Do the same thing with hero points, but separately.

If the roll indicates the character is about to erupt, the character can accept a -1d penalty to all future damage soak rolls. This allows the character to delay eruption until they earn another 10 character points or hero points.  You can only do this as many times as you have dice in Might.

If the character is about to erupt and cannot or will accept the penalty, they can delay eruption using character points or hero points. 1 character point delays eruption for 1 round. Hero points delay eruption for 10 rounds.

When a character erupts, everything within a radius in feet equal to the characters total character points takes damage equal to the characters total character points. Additionally, everything within a radius in feet equal to the characters hero point total takes damage equal to the characters hero point total.

Marked within the radius of the eruption who survive gain a hero point. These characters may roll 1d6 and gain that many character points. Unmarked in the radius who survive have a chance to gain a mark equal to the erupting character hero point total.
