Manipulating passive defensive stance
When you have no target for over two seconds you will passively gain defensive stance, without touching the stance toggle. There are several techniques to exploit this mechanic so that you attack on attack stance but receive damage on defensive stance. Note: this is not the same as stair hopping in later versions of tibia
- As the monster approaches, do not target it, instead wait for the monster to attack you first. A targeted monster will have a red square. When you block this attack you will have passive defensive stance.
- Now you have blocked, target the monster to return the hit on your current stance - full attack is reccomended.
- As quick as possible un-target the monster. You can target and untarget quickly by double clicking.
- Move a way to create distance between you and the monster to prevent it hitting you before your passive defensive stance has reactivated.
- Wait at least two seconds for passive defensive stance to reactivate, then repeat step 1 - blocking the attack.
The simplest technique is to stair, ladder or rope 'hop'. By changing floor you automatically un-target and the monster will always attack you before you attack them. Wait for two seconds while upstairs and repeat this in a rhythm as close to, but more than, two seconds as possible - likely 2.3-3 seconds per cycle. Too fast and you will start taking hits on attack stance, and take more damage. Too slow and your attack speee goes down significantly. For rope spots it only works to go up from the lower floor to attack.
In the below example a knight would kill the dwarf guard in an average of 6.0 hits (14-18 seconds) and take 23 damage in total. Compared to balanced mode without stair hopping, the knight would need 8.6 turns (17.2 seconds) to kill and take 92 damage.
That is one quarter the damage taken in the same time!
As skill, gear, and magic power develop to reduce healing expenses it becomes less useful to use this technique as the slower attack speed compared to just full attack reduces the loot and exp. A high level knight can still benefit without the speed reduction by waiting for the first hit before targeting.

An intermediate technique is to use corners to exchange hits then run to get an immediate one tile gap between you and the monster as they still need to turn the corner. You can do this while luring or chain these together in a circle if there are some obstacles sized 2x2 or bigger.

If you're in an open area with no stairs, ladders or corners you can just try to outrun the monster while recharging passive mode. This is less reliable with low speed characters since initially you will cycle between a 1 and 0 tile gap. You can improve your head start by attacking as soon as the monster starts to move into the tile adjacent to you - in game code you immediately move to the new tile and the animation just shows it retrospectively, by attacking then moving early the monster will have to wait for its step delay before chasing you. This works better on fast tiles but also takes up a lot of space.

The final and most advanced technique is to take advantage of the fact you only need to have a gap between you and the monster between the time the monster has recharged its attack and when your passive defensive mode has reactivated. In a nutshell it can't attack you for two seconds! Say the monster is on the adjacent northeast tile, if you take a diagonal step to the southwest you will instantly have created a 1 tile gap, so the creature needs two steps (one whole step time) to reach you - if your passive defence reactivates in this time the trick will work. This works better with slower tiles.
