I've been digging into the new Sneak rules for my stealth character in G13. There are a couple things I am curious about.
As with any check where a skill is opposed by a SPECIAL, the character using the skill rounds up for determining degrees of success.
This at first confused me, making me think the sneaking character rounded their roll up. This incorrect reading is opposite the "Skill trumps Natural Ability" standard for the system. I set myself straight by looking up opposed rolls for validation, but somepony could argue the other way if they are only checking the stealth bookmark. For consistency, I think there should be some of the "...making the Skill test divides their degree of success by ten, rounding up..." verbiage used here.
+2 for variance seems high to me. Especially when I consider low levels and my question below.
I'm curious what constitutes a group. Is a group simply more than one? If two ghouls are milling around, is the check made at 7 (4 base+ 2 variance +1 additional member)? If so, that makes sneaking at low level seem very difficult.
On the flipside, is there a consideration for setting guidelines for how to split a group, or leave it strictly GM discretion? The split seems incredibly important for how difficult the check is to make. Maybe consider giving some variety of options for GMs to choose from? Like:
Overflow Method - An enemy group's member bonus should not exceed +5. For groups larger than six, split the enemies into groups of six with the remainder forming the final group.
Even Split Method - An enemy group's member bonus should not exceed +5. For groups larger than six, split the enemies into even groups so that no subgroup's member bonus does exceeds +5.
Example
The Core Rules example appears to use the Overflow Method (OM). We'll compare the Even Split Method (ESM).
Using 8 ghouls: OM= +5|+1 (6 ghouls | 2 ghouls) ESM= +3|+3
10 ghouls: OM= +5|+3 ESM= +4|+4
15 ghouls: OM= +5|+5|+2 ESM= +4|+4|+4
In my experience, generally GMs like options, Players like rules. Thinking like a player, I'd like to see some guidelines in place. GMs will still do what they want, but having methods in the book might keep a GM from deciding "I want them to succeed, I'll split them this way" or "I need them to fail, I'm not going to split this group up at all". Anywho, my two cents.
