The effect of Saber stacks with the effects of Steel as well as itself.

Saber is an absolutely fantastic Spell—just not for the Black Wizards that can cast it. It will significantly increase your offensive prowess, but it's far from enough to make Black Wizards useful in melee. In any case one shot of Ice3 will almost always deal more damage than you'll actually get out of Saber. On the other hand, the Giant's Gloves let any character cast Saber on himself, which for actual melee characters is quite powerful. If you don't mind abusing the system a bit, multiple castings of Saber will continually increase your number of attacks as well as your per-hit damage, transforming any character into a killing machine.

The effect of Steel stacks with the effects of Saber as well as itself.

Steel is a fantastic Spell, even if you don't stack it with itself (in which case it is frankly unfair). An ally affected with Steel will deal out 14–28 more damage per hit, which is a huge amount early in the game and adds up quickly when you're making multiple attacks later in the game. Combined with Haste, you can make any character into a damage-dealing machine. This Spell is fantastic against any enemy with high defense, especially bosses. Don't miss it!

While in later versions of the game, SABR is the key to putting major hurt on bosses, in the NES version this Spell is just riddled with bugs. Like TMPR, it doesn't actually do anything. Not only that, but even if it did work, the Hit Rate bonus would be (wait for it...) zero. Not that you'd want your Bl.Wiz to buy this Spell anyway, but on the NES the Power Gauntlet isn't even worth keeping. It's a sad state of affairs.
