The maximum Force of the spell is your Magic Rating, and the Drain is always physical, resisted with Body + Willpower. This ability otherwise follows the standard rules for spellcasting. The adept can take ranks in the Spellcasting skill and is required to take at least one rank to use this power. This power can only be taken once.

POWERBLADE
Type: P Range: Special
Duration: S DV: F – 2
Spellblades are a product of a failed line of research by MCT. Attempts to create a sustained damaging connection of energy failed to yield the desired results, but they resulted in a maintained extension of a spell, based on the formulas for Manabolt and Powerbolt. These spells could yield a field of energy roughly the same
space as a sword, maintained for as long as the caster could concentrate. The formula was altered to allow the caster to “hold” onto the spell at a point analogous to a grip, though the “blade” portion of the spell remained dangerous. It was found that these blades could parry one another and could cause repeated damage, strike after strike. As this did not meet the requirements for the project, it was abandoned, and the formulas sold through backchannels to recoup losses. One formula fell into the hands of wizgangs, where they quickly gained popularity for their showiness and the skill needed to maintain and wield one. Duels and motorcycle jousts with blazing energy have become the new fad among these Awakened youths. Shadowrunners and assassins with a talent for swordplay may appreciate the blades for their additional damage potential, as well as the ability to summon a blade anywhere without trying to smuggle it into a secure location. A Powerblade operates on the same principle as a Powerbolt or Powerball, affecting physical objects, capable of parrying and resisted by armor. A Manablade works like a Manabolt or Manaball, bypassing armor and capable of affecting spirits, but unable to parry physical attacks or damage objects. Note that weapon foci are able to parry Spellblades of either type due to their magically active nature. Spellblades can only be used by the person who casts them; they cannot be cast for anyone else to use. The range of the spell, then, is limited to the caster, though the spell can affect anything it touches once cast.
The damage for the weapons created by this spell equals to the Force plus the net hits rolled on the melee
weapon skill of the wielder’s choice. (In spite of the name, the Clubs or Blades skill works equally well). The
Accuracy of the Spellblade is equal to the Force of the spell, and the Reach is 1.

That's a problem? Obviously Combat. It is designed to hurt and damage. In SR5, that's always Combat.

Having to rely on Orgasm has hurt the ego of quite a few mages as well... Does that count?

Know at least one of those guys... He is a very disturbing magician indeed...

Yet he is still very popular with all of his partners.

Must be exhausting...

But one problem still remains, as far as I know: To what school do Powerblade & Manablade belong to? Combat or Manipulation?

Take a qi focus and combine it with a sustaining focus - and voilà, a magical light sabre. Buy both at level 4 for 28000 Nuyen and 16 Karma during character creation and be the jedi adept you've always wanted to be.

Combat spells are always Instant in duration; they may not be Sustained or Permanent.

One power point to become a seriously limited MysAd? Make it count, and make sure it has style. You probably also want a spell you'd overcast (physical drain either way) or easily ignore the drain of.

Unless they've changed the spell design rules in 5th edition, it can't be Combat because it has a duration of Sustained. Last I heard, they hadn't even republished spell design rules in Street Grimoire, but if we go off of Ye Olde Street Magic:

If it makes you feel better, the Manipulation category of spells impinging one what folks have perceived as Combat's turf is something of a time-honored tradition in Shadowrun. Examples could be multiplied.

Well, Flamethrower and Lightning Bolt used to be Manipulation spells in SR3 before they became Combat spells in SR4.

And in one of the SR5 supplements there is a sustained Combat spell: Shadow Spells, page 16, Flame Burst. The old spell design rules of SR4 were trashed the moment SR5's magic was done, which is obvious if you pay any attention to the current Drain codes.

This sounds like something in desperate need for some errata.

Why do even the topics with funny intentions get dragged into edition complaining? This is why we can't have nice things (and I remember to post in other forums).

Nostalgic whining does not lead to errata. Addressing current edition rule issues does. Those are two very different things.
