If you wish to distribute pre-paid cards however, it's not allowed if your recipients do anything in return for the code. This includes but RS gold is not restricted to, giving you in-game items, giving you real money, or having them click links (and similar schemes) in order to get a referral somewhere. In fact, for the players to do anything other that simply accept the code would mean it would not be allowed.
If you're talking about an opportunity to sign-up whereby people could sign-up, and you draw random names and send the winners the prize (with none of the strings, or just the code) Then that could be considered to be acceptable.
Giving away a charity item is appropriate. A trade of favours however is not. Yes, I am talking about subscription codes. I've got around seven Subscription Codes (I think , but I'll need to confirm) that I wont use so I decided to give them for those whom cant afford to buy one
I was thinking of doing it such a thing: Create a thread regarding the giveaway and then I will post questions such as. What is the reason I should give you a Membership? Why do you like Runescape? What do you plan to do with the Membership? These questions will make it simple for me to pick a winner and also to hinder members from selling their codes or to stop lazy spammers from receiving the codes.
"Normal" (as means not Nex) GWD armour is adequate to complete Slayer tasks. It's not expensive (for someone with your resources) It doesn't require to be repaired or replaced, and it gives offensive bonuses. You should have an Barrows set that includes every type of combat (Verac's Ahrim's, Karil's, and Verac's) to complete the few Slayer tasks which require the highest level of protection.
Glacor boots are the best boots that are still available. Barrow gloves aren't that good anymore, they're hybrid gloves so they have some uses however, if I were in your shoes I'd choose the TWW Automaton gloves (Static Pneumatic, Tracking and Static). They're the gloves equivalent to Glacor boots.
Amulet Of Fury remains a good amulet, the best hybrid amulet in fact. But if you have money to spend , you might want to invest in a Saradomin's Hiss (second top magic amulet ahead buy old school runescape gold of Stream Neck), Murmur (currently the top melee amulet on the market) and Whisper (best ranged amulet).
