I are here to gibe feedbek to ResQ as ReQested!
-Upheaval(warlock) should be added either some damage for stacking with infernals and fatal bond just for original warlock build,or either some healing ability considering that original hero also is healer,by that way it could either harm opponent for period of time or provide some healing to allies while enemies are slowed,or maybe add -attack speed aswell.
-Anti magic shield(magina) should be added cast effect,similar to linken sphere,you transfer your 50%magic resist on ally hero for a period of time,by time you are weakened your ally has +50% magic resist,until time passes.
-Null field(rubic aura) should be redesigned similar to trueshot aura,it is passive all time but once activated you and nearby units are granted with magic shiled,which would be like crimson guard only for blocking magical damage.
-Gust(traxex) should be added pure dmg,like 25/50/75/100.That way you would have excellent small cooldown,nice push and silence ability with minor dmg which would do well with mc or witchcraft builds.
-Silence(krobelus) should be added some damage per second and/or slow,for instance 25 damage per second of silence(which would be 150 dmg on level 4) and it would be nice for crowd control combined with other low mana controls spells such as vacuum,kinetic field and pit of mavalence or however it name is.
-As mortred dagger gains ability of your attack booster from item,Spectral Dagger(spectre) could be granting you to trigger your attack boosters from spells you have picked(greater bash,bash,mana break,poison sting,geostrike,Frostmourne,Swipes,Desolate) it wouldnt be buffed that much but at least would give you first extra blow to maim your target or even for your finishing blow.
-Death pact(slark) can be added some slow/miss effect and/or not costing caster any life.Or changing damage type to pure.
-Death coil(abbadon) same as previous.
This is some soooo underpicked or neverpicked spells i could think of,if i come across more ideas i will give more feedback.
