Round 2 of Secret Jackalope. Fear not Phlox! You have called and I shall answer. The following rules are Mosaic Strict.
What qualifies as a giant?
Giants are creatures large enough that they can be climbed on by human sized characters, an who are normally highly resistant (if not immune) to regular damage sources by nature of their tough or magical exterior. Giants include but are not limited to titans, massive dragons, krakens, and mecha.
How do Giants Fight?
Giants have a variety of ways to kill the things that bother it. While these methods vary we refer to the action of utilizing these methods as Squashing the Vermin and they are usually all very lethal. Giants have a 5 out of 6 chance to immediately kill whatever they decide to within the targeted area of their specific method. This chance can be reduced by the targets to a minimum of 1 in 6 by benefiting from: Concealing Cover(-1), Protective Cover(-2), Siege Cover(-3), A significant distraction (-1 or -2), Damage that’s just been dealt(-3), Hindering The Beast(-1) or Immobilizing The Beast (-2), Improved 2D Mobility(-1), Improved 3D Mobility(-2).
How does one damage and kill a Giant?
Giants are not invincible. Giants have highly specific “Weak Points” (WP) on its body somewhere, usually 1, 3, or 4 although more is possible. One must inflict enough damage to kill a human with whatever weapon is normally capable of killing humans in your setting to each WP before a Giant will go down. Generally, weapons capable of destroying buildings in your setting is also significant enough to reduce a giants WP by 1 (to a minimum of 1). Any weapon capable of doing so will usually be immediately prioritized for destruction by the Giant.
Weak points are very rarely at ground level. Thus people must either Scale the Beast or Aim Carefully in order to strike a Weak Point and deal Damage.
Attempts to Scale the Beast generally have a 1 in 6 chance of succeeding. These odds can be improved up to a maximum of 5 in 6 by: Using Appropriate Climbing Gear +1, Mounting From an Elevated Position (+2), Hindering the Beast(+1) or Immobilizing The Beast (+2), Scaling Unnoticed (+2).
Attempts to Aim Carefully has a 1 in 6 chance of succeeding. These odds can be improved up to a maximum of 5 in 6 by: Using a Static mounted Weapon +1, Aiming From an Elevated Position (+2), Hindering The Beast(+1) or Immobilizing The Beast (+2), Attacking from Stealth(+2).
Attempting either of these two things takes time, enough time that the giant may attempt to Squash the Vermin. If the Giant fails to do so, then damage is dealt automatically.
Kaiju Fight Club
If one Giant fights another Giant, they deal damage to each other as per whatever regular combat resolution methods you utilise for human on human violence. If a Character is Scaling the Beast while the two are locked in combat, they must deal with 1 attempt to Squash the Vermin. Either the Giants are striking each other and one has to avoid friendly fire, or the Giant you are scaling will attempt to deal with you in a spare moment.
Lethality
The rules here are very lethal. For more heroic games, have attacks not instantly kill but instead instantly down someone, or allow chances for Squash the Vermin, Scale the Beast, and Aim Carefully to be improved/reduced to 6 out of 6 and/or 0 out of 6.
