Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
So for no particular reason whatsoever, I was thinking of anime blasts
and how to simulate them with ORE (Wild Talents to be more specific).
Let's say the giant mecha Grand Knight wants to unleash his magical
Plate Buster Attack and at the same time Magical Girl Yuki fires off
Giant Beam Strike at the knight.
Both of them roll their dice.
If one beats the other's Width, it's all over - the faster one hits the other first.
If they tie for Width, both beams collide somewhere in the middle and
we have a little minigame on our hands. We first establish who has the
lead by comparing Height.
The Higher roll gains lead equal to the difference in Height while the
lower roll gets a negative lead instead. So lets say Grand Knight gets
3x8 while Yuki gets a 3x5 - this means Grand Knight has a +3 lead while
Yuki is trailing by -3.
Next round, they must maintain their beam (i.e. by declaring and
rolling the same attack again). If either side decides to do something
else (or fail their roll completely), they get hit by the beam at a
strength equal to the original Width of the attack, and at a Height
equal to 5+lead.
If both sides maintain their attack, they roll and compare results
again. Any Width or Height advantage modifies the leads accordingly,
until the lead hits +5. The loser gets hit by the full (Original Width)
x 10 attack.
Always compare and apply Width before applying Height, in situations where Width is enough to gain victory.
So let's continue with Grand Knight and Yuki's battle:
Round 1 was GK +3 / Yuki -3.
GK rolls 3x4.
Yuki rolls 3x6.
Yuki pushes harder and her beam gains more gound, pushing GK's beam away. GK +1 / Yuki -1.
GK rolls 2x2.
Yuki rolls 4x3.
Yuki gets +2 from Width, and another +1 from Height. Her beam continues pushing GK's beam back. GK -2 / Yuki +2.
GK rolls 2x10.
Yuki rolls 5x2.
GK prepares to unleash his ultimate strike, holding back just a while
to gather his full energy to knock out Yuki once and for all. But Yuki
quickly takes hold of the situation and pushes forward before GK can
react, and reaches +5 from Width alone. We don't need to look at Height
GK gets a full 3x10 blast in his face (since the match started at Width 3).
