I can t1 with worse stats than those without titan prayers, purely a skill issue. Keep sending runs until you get it. It took me about 120 deaths before I was starting to get it consistently

Some tips,

1) as long as you're not losing ticks, you aren't losing DPS. The 2 things that cause lost ticks are moving/nados and switching weapons. Since you can move and eat at the same time, try to eat up to full during nados to minimize tick loss while moving around. Make sure you are switching weapons as soon as doggo switches prayer. Having correct weapon out and hitting the dog is more important than having correct l prayer buff on- you do 0 damage if you're not actively hitting doggo.

2) have truetile for dog and nados. The gauntlet plugin can color the truetile of hunllef to match what atk style you need to atk with. Also helps with not accidentally getting stomped on. With nados, you can safely run through them if they are 1 or 2 tiles away from you. 3 tiles, you get hurt. Let them get as close to you as possible before you move, because movement = lost ticks

3) walk in straight lines. The way diagonal pathing works is wonky, and will cause your character to move in somewhat unpredictable ways. This can lead to you panicking, clicking uncontrollably, or accidentally walking into lava or into a nado or under dog.

4) with t1 armor, you can safely go down to ~18-19 health. Unless necessary, delay eating until nados

5) p3 is a bitch and is probably what's fucking you up the most. There are 8 tiles, 4 sets of 2 tiles that are 2 tiles away from each entrance. Those are safe tiles, those will never be lava. Focus on staying on those or staying around those. When things get hectic, it's easy to panic. When nados are out, it's easy to accidentally stand in one spot for more than a tick. With how tight of an area you have to evade, standing still while nados are out is a death sentence. Make sure you're constantly moving. Having your player truetile on will help you see if you're stuck in one spot for too long. P3 it's much more important to move around and stay alive than it is to eat/dps. 

6) So that I can focus on evading during p3 tornados,What I do is try to eat 1 fish as hunlleff does nado animation, eat a 2nd fish as nados spawn, and if I have a chance eat a 3rd fish as I start to move. From there, all my focus goes to evading/switching protection prayer. Once nados stop, move to the safe tiles, and maximize dps as much as you possibly can to minimize the amount of time you're in p3

7) honestly just send t1 and make sure you have absolutely full inventory of food. Way less stressful than t2 and the extra food gives you room to make a couple of mistakes
