The aggressive style adds points in Hitpoints and Strength, and OSRS gold defensive in defence and hitpoints. The controlled style can earn points in all of the above at the same time. As you can see, choosing the wrong combat style once could result in a decrease in ability and, consequently, damaging the Pure aspect of the account.
Another risk to the purity of account lies within quest rewards. If you want to be pure have to be more attentive to the rewards they are awarded at the conclusion of NPC missions. These quests typically offer the highest amount of experience in certain of the skills, so they can be very effective to level up, but they also might be a fatal stray for a Pure player. If you've chosen to improve only certain aspects should always pay careful attention to what reward they might get at the end of a mission.
One Defence accounts are likely to be the most common of all Pure characters. They are intended to be killing machines for Player against. Combat between players. Because the ability to defend isn't as important in PvP as it is in PvE, players usually skip leveling it, leaving it at the initial level. In doing this, they'll attain a low Combat Level and still maintain high damage output. The players who are looking to challenge them normally won't be expecting very high hits from the lower level opponent.
Even though creating One Defence Pure is very time consuming and sometimes might frustrate, the process always benefits players in PvP. The majority of players who take this route utilize their Pures exclusively for killing and not for regular gameplay since using one Defence and Low Prayer levels almost exclude their ability to do high-level PvM content.
Don't be confused by this one - it is exactly opposite to One Defence Pure. It's also an account that has the lowest Combat Stat, but in this case, the owner chooses to increase Defence Skill but buy rs3 gold at the expense of other characteristics.
