There have been numerous discussions similar to OSRS gold this one before, but now its my turn. My friend quit today, he offered me all his money, I wasn't keen to accept it but he forced me to. In the end, I have a 43m budget. What kind of armor should I buy? Please include boots and gloves and even a weapon in the event. Let me know how great this is , and how much above my budget this would be (Use the ring of a berserker and dfs included) and also suggest any other thing to consider changing.

There isn't any one skill you can train to be a good one. Each of them is useful to some degree, and only focusing on one of them won't help you in the long-term. However there are a few suggestions and their reasons:

Construction. In the event that you are able to have an area for portals or a menagerie as well as a prayer altar, this is extremely beneficial. The portal room can be extremely beneficial, especially for those who are just beginning their journey as an active member. All the teleports that you'll need are there. The POH is also great for storage, storing almost every tool, most books, as well as lots of other clothing and armour.

Agility is also extremely useful reaching 21 is essential to ensure that you can use the Varrock-Edgeville shortcut. Also, getting higher levels is extremely beneficial for battling monsters, large quest areas as well as PKers (true experiences there). At least 21 should be among primary things that you try to do.

Summoning is a fantastic skill, but you can't achieve it in a hurry. If you haven't already completed the 43 prayer, you can unlock it with penguin points as well as the troll invasion DnD and put these into summoning. The ability to obtain a spirit terrorbird (level 52) is extremely beneficial and helpful. What I'm trying to say is...always pick up your charms. It's never a good idea to buy OSRS GP leave them on the ground.
