The Top 10 F2p Monsters to Train On

1. Lesser demons (Level 82) - Karamja Volcano (or Crandor Island) These demons have a low attack and defense level, have around 80 hp but can hit 8s without any weapons. They have relatively good drops and give great xp for mid to high level players, usually dropping from 40gp up to a rune med helm (usually happens once every 200 kills or so). There are several hiding spots for mages and rangers to use and the demons will become non-aggressive after around 10 minutes. If there are too many people, you can switch worlds or go to a german server (usually with 50-500 people).

2. Moss giants (Level 42)- Eastern Ruins (Level 30 wilderness), Crandor Island, or Varrock Sewers

Moss giants are usually level 42 but can still hit up to 5s. They always drop big bones (worth around 300gp each) and can also drop black kiteshields, mithril stuff, magic runes, and a few other items. It is however not recommended that you go into the wilderness because of the revenants that can annoy you or even easily kill you (level 7 revenant imps can hit 8s!).3. Cockroach Soldiers (Level 81) - Stronghold of Player Safety

These are level 81 but are way stronger than lesser demons. They can hit up to 13s and will use whatever you use at it, so it'll range you if you range, it'll mage you if you use mage, and it can also melee you. However they have very high defense and are recommended for only very high leveled players but can drop a couple different rune items, magic runes, etc. Fortunately, they are not aggressive, unlike the lesser demons and moss giants mentioned earlier.4. Hill giants (Level 28) - Edgeville Dungeon

Unlike the previous three, hill giants are a low level 28 but still drop big bones every single time, like the moss giants. They can also drop limpwurt roots, other steel items, runes, and various cheap items. Like before, if it is crowded, then change worlds, preferably onto one of the German servers.5. Minotaurs (Level 10 - 12) - Strong of of Security first level
