half load: up to this limit can be carried without problems
75% load: up to this limit can be carried with -5 running speed (not moving speed), -1 agility tests
max load: up to this limit can be carried with -10 running speed and -1 dice in melee (when attacking or defending) and -2 on agility tests
jump: base jump distance, unless the varan has Strong legs (+3/+6). Reduce by -1/-2 for each full 20kg carried.
If the running speed would be reduced below normal movement speed, both are reduced to same level. Note that varans can carry more than max load if need to, but only for shorter periods of time. The armor value is reduced to 4 in such a cases (still 6 if the varan is not clearly seen)
