One of my players has asked me if he can use the abilities Mind Over Matter and Precision Telekinesis to do the following:
-Use melee weapons at range (imagine a floating sword)
-Throw grenades (imagine again, a grenade floating and removing its pin at range, at the psyker's will, or simply tossing it with mental power)
Unlike the first gross manipulations of Telekinesis, this allows the psyker to fine tune his ability until he can do anything at range that he could do with his bare hands. In any situation where the task in question would require a Characteristic Test, the psyker substitutes Willpower instead. The psyker’s Psy Rating substitutes for his Strength Bonus when using this technique.
About this ability, I'd specifically want to know about in what situations can the psyker use WP instead of other characteristics to make tests. Does this rule include combat, attacks?
Mind Over Matter (it's a long one):
Telekinesis is the ability to move physical objects with force of will. The psyker’s initial gift in Telekinesis has several applications. The psyker may lift or move any object within his range and line of sight that does not exceed the weight limit of 10 kg x Psy Rating. The object may be moved slowly within the range of the power. Objects move far too slowly to be used as an attack, however. Additionally, this raw lifting ability does not function on living beings, as the smallest movements tend to unbalance the psyker’s mental focus. Once an object is released from Telekinesis, it begins to slowly settle back to earth as the last vestiges of the power leave it. A more forceful approach can be taken with lighter objects, weighing up to 5 kg x Psy Rating. These may be accelerated with greater speed and force, out to a maximum of 5 metres x Psy Rating. To hit a target, the psyker makes a Ballistic Skill Test. Damage is equal to 1d10 Impact Damage plus 1 point per 5 kg of the missile’s weight. Lastly, the psyker can direct a sharp wave of force against a target to shove it away. The psyker must make an Opposed Test, pitting his Willpower against the target’s Strength. If the psyker wins, he knocks the target to the ground and pushes it away a number of metres equal to his Psy Rating.
About this one, could you combine its use with a grenade, so the target would receive the damage from the grenade impact, plus the explosion of the grenade itself?
