House Rules

(life under the sea)

Combat

• The segment in which you attack (1-10) is based on:
  
  weapon speed - dexterity modifier + initiative roll score

  weapon speed and dex mod are on the character sheets
  initiative roll is d6: (1=+2, 2=+1, 3 or 4=0, 5=-1, 6=-2)
  

• You can change your declared action in a round, but must make a dex check, and all attacks must be declared before the start of the 6th segment.

• Critical hits: If you roll a 20, roll d20 again. If the 2nd roll is a 19 or 20, you do 2 dice of damage and roll again. If the 3rd roll is 18,19, or 20, you do 3 dice of damage and so on.

• Critical misses: If you roll a 1, make a dex check or fumble your weapon.

• Binding a wound takes a full 10 segments.
  

• Thrusting

  Weapon	Speed	S-M damage	L damage	Special
  trident	7	d6+1	3d4
  spear	6	d6	d8	can be thrown
  javelin	4	d6	d6	can be thrown
  dagger	2	d4	d4
  barbed dagger	2	d4+2	d3+2	if hit with 17+, Open Doors in 10th segment to remove and roll for damage again, else stuck until end of combat. Cannot use dex AC bonus while holding on.

• Missile

  Spears and javelins can only be thrown underwater with the aid of a spear thrower, which takes a full 10 segments to prepare. This can be done before the first round if there is time to prepare. Spears and javelins get both strength and dex bonus to hit when thrown.
  

  Weapon	Speed	S-M damage	L damage	S range	M range (-2 hit)	L range (-5 hit)
  spear	16	d6	d8	5'	10'	15'
  javelin	14	d6	d6	10'	20'	30'
  crossbow	2	d4	d4	20'	40'	60'

• Net
  

  Nets are 6' hexagonal with 1/2 lb weights at the 6 corners and have mesh that is 2 inches square. They are thrown in combat with speed 8, but require enough room to throw. They may be thrown a number of feet equal to the attacker's strength. If the defender is hit, but not surprised, they may make a dex check to avoid the net. The range modifies the save (1-5ft=-1, 6-10ft=0, 11-15ft=+1,16-18=+2) and if the defender performed any other non-dodging actions that turn, the save is at -4.
  

  The victim of a net attack is trapped until 1-2 rounds is spent gaining freedom. While trapped, they suffer -4 AC and -4 to hit.

Spell Memorization

Spells of 1-2 level require 4 hours of rest and 15 mins/spell level

Spells of 3+ level require 6 hours of rest and 15 mins/spell level

Movement

• Running 300 ft/minute
• Forced march 200 ft/minute
• Regular speed 150 ft/minute
• Searching 100 ft/minute
• Very cautious 50 ft/minute
  

  When you tell the DM your movement, remember to include the third dimension. If you don't tell us you're swimming up or down, we'll assume that you're staying on the same level. Think of it like flying!

Mass

Objects have the same mass as you're familiar with, but we'll consider "weight" to be the force gravity exerts objects relative to support from the water. The weight of an object depends how bouyant the object is:

Bouyancy	Relative Weight	Max Fall Rate (depends on shape)
Very (balloon)	-normal	-400'/min
Quite (wood)	- 1/2 normal	-200'/min
Sort of (witches)	- 1/6 normal	-100'/min
Even	0	0
Sort of solid (you)	1/6 normal	100'/min
Almost solid (clay pot)	1/2 normal	200'/min
Solid (rocks)	normal	400'/min

Sea-humanoids are "Sort of solid", but many of the things you carry are solid, so the average is somewhere around 1/4 relative weight.

Misc

• Mapping can only be done at Searching speed.
• If you request the DMs to enhance your maps, you can only move at Very Cautious speeds.
• All light sources are 40' underwater.
