Fragmentation Grenade

Built on the chassis of RMU's own Ball attack table — the same 37 bands of 3 a weapon table uses, moved 50 points down the roll axis. That shift is how RMU encodes an attack that adds only its rank count instead of an Offensive Bonus: the ceiling drops to 125 rather than the roll being penalised RMUCore Law 9.3 (p. 164) gives area attacks no attack skill, only the level of ranks in the originating list. Spell Law's Fire Ball resolves on the Fire Ball Table, and all three Ball tables (Fire, Cold, Lightning) run 15-17 to 123-125 against a weapon table's 65-67 to 173-175. Ball, Fire and Bolt, Fire are near-identical at the same band index (+1.2 hits), so a ball is its bolt with the axis moved.

One roll for the detonation, then each target subtracts their own Quickness DB and applies the band modifier for where the grenade actually landed. Criticals are rolled separately per target, so one burst opens one man's arm and another's leg RMUCore Law p. 175: criticals from one area effect are rolled per target rather than once for the group, so a Fire Ball can burn one target's arm and another's foot. The GM may roll once for a large group to save time. The full procedure — placement maneuver, scatter, the blast bands and the fuse — is on Combat.

A critical against Kindred lands one severity level lower. This table reaches G, and a result above E is an E critical plus a second one taken from the second critical type listed: an F is Shrapnel E plus Ballistic Impact A, a G is Shrapnel E plus Ballistic Impact B. Both land on the same body location — fragments and blast in one wound RMUCore Law p. 175 and Table 9-8a: F = E+A, G = E+B. Where an attack table lists several critical types they are used in the order listed, and every critical from one attack shares the same roll and therefore the same location. Fragments first and blast second is this conversion's ordering. The BA I-IV columns price how well a vest stops a fragment; whether it was standing in front of the part that got hit is resolved per area by Ballistic Shrapnel's own covered and bare clauses.
