All moves you learn from the levels 1-7 are custom moves; That means you are free to invent an effect for its working, following a few basic rules. Below, I'll post a small guide for you to understand how customs work:

A Crude Order of Power: moves < learning ability < racial ability < racial quest < racial move

No move can have more than two distinct effects and this may only happen if a drawback is given them. An easy way to classify moves is: Lv 1-3: basic. Lv 4-6: advanced. Lv 7 ultimate. Below, I'll post some examples of effects based off each level. The higher the level, the better the effect:

Lv 1
A note on this; remember that level 1 moves can only have an effect if a drawback is given. In that case, you can use it 5 times per battle. Common examples:
Channeling: The ability to shoot energy from parts of your body other than your hands { i.e: a mouth blast }
Untrackable: Will give a -0.3 penalty to the target's sight speed to spot the move.
Area of Effect: Affects anything in a radius of 1 mile per 100.000 base pl. Max of 10 miles.
Piercing: Will pierce through anything up to your pl / strength x1.3. If the piercing doen't work, the energy will barely burn the target.
Controlling: May control the course of your blast using the movements of your hands.

Lv 2
Slicing: Will go through anything up to your pl x1.2. If the slicing doesn't work, it won't do much other than a weakened impact force.
Blocking: Can block anything weaker than your proper pl / stat.
Drain: Can drain 5% pl per post you hold your opponent trrough touch. Every 5% is converted in energy soruce, restoring one
            useage of a limited uses move of your choice  { from your basic move list; doesn't include quests or abilities or the
            ultimate move } .
Homing: Your attack naturally homes in a target. The opponent must be x1.3 times your speed to make the attack crash back on yourself.
Disabling: For as long as you hold your opponent, he/she can't move. You can't use other techniques. Your strength must be greater than theirs by any amount.

Lv 3
A note on this; Effectless level 3 moves can be used 5 times a battle; With an effect it can be used 3 times per battle. Common examples:
Bone Breaking: Instantly breaks a bone of a target if his strength is below yours. Depending on where you hit, it has a different effect:
                               Head: Faints { very easy to dodge; target's speed goes to x1.5 times higher to dodge }
                               Torso: Pl / Str defenses -20% until healed.
                               Limbs: Using that limb will imply in damaging yourself at your own pl / str in that very same area { easy to dodge;
                                          target's speed goes to x1.3 times higher to dodge }
Paralysis: Will instantly paralyze someone upon hitting:
                   By a couple of seconds { enough for an attack to get through } : if pl is up to yours x1.3
                   By 1 post: if pl is up to 75% yours 
                   By 2 posts: if pl is up to 50% yours
                   By 3 posts: { enough for an attack to get through } : if pl is up to 1/3 yours

Drawbacks
Reinforcing what was previously said a drawback allows the addition of a new basic effect { remembering basic effects are those from lv 1-3; and naturally, you can't add a lv 3 move to a lv 1 move, if it isn't a very extreme drawback } or the improving of an already existant effect of the move. Common examples:
