Really wish I could give a good answer to RuneScape gold this question but I haven't done the study since the battle improvements upgrade which shifted many abilities. The problem is that Jagex has really, really terrible communication between their writers and code guys, and both website and ingame descriptions are often completely false in contrast to the real code. An example of this is Wild Magic pre combat improvements: Its ingame and website description states that it must do between 25 percent and 250% damage, while in reality it did 73 percent -219% harm. You will find many other mislabeled skills pre combat enhancements.
Many skills are probably still tagged wrong, but I unfortunately don't have the information. Another thing I would have to know is the suitable recharge times of skills. Jagex has an incredibly annoying insistence on using moments, rounded imprecisely, rather than using decimal values or just calling it"game ticks". Additionally, you really should NOT be requesting pkers about dps since dps is of hardly any importance in pking - it's about stuns, defensives, prayer disrupts, and high burst damage combos. If you attempt to pk someone with standard pvm strategy they'll tank you .
I just purchased the Spider Orb in the Grand Exchange and utilized it in battle beneath the Barbarian Village. The very first thing I noticed is that the cartoon seems to indicate the spell is coming out of the Spider Orb (And maybe not the Spider Wand, that I have outfitted ). It takes 20 Magic to wear. It is the off-hand equal of the spider wand, and it lets players cast spells with the off-hand slot."
What I do not understand is: it's the off-hand equivalent of the spider wand. It allows players cast spells using the off-hand slotmachine. What does this mean precisely and if I even bother using it at all? And, I don't know what"off-hand slot" means. Well as I'm confident you've noticed players can dual wield weapons today. Previously (like in pre-Evolution of Combat) besides two handed weapons that your only choices were to use a one handed weapon with a defense or a somewhat offensive shield slot thing like a Defender or a God book, but they were still shields in theory.
Dual wielding is more offensively focused of course, and it's slightly better than using 2handed weapons since you get somewhat better abilities. That is the reason why most people prefer using double crossbows rather than a 2handed crossbow or bow, and a wand + the defense slot offensive weapon equivalent (usually orbs like the Spider Orb) rather than staves (except in certain circumstances where you ought to OSRS buy gold risk just one thing ).
