By now most of you already know how to chain and combo weave into your chains. If this is something you do not know how to do, I'd suggest you learn and practice that first before attempting this strategy. You should also know how to setup lag chains or implement them while you do not need to be adept it helps.

For V-hard stages, spend the first 8-9 seconds building as much as you can, when it comes to both chains and combos, try to be more combo heavy than chain heavy, try to cap at x6 for chains. After that wait 3 seconds and send a combo at 11-12 seconds to ensure the kill. Just 1 combo will do.

Ideally you will send an x4 with a 9 combo or an 8 but no 4's on the other combos, so as to have 4 lines of combo garbage and 3 chain combo garbage for a total of 7 lines. this for the first 4 stages

For Frog Blarg and Fish you might want to send an x5 just for safety, these guys clear quickly and if you catch them on the low you will need more lines and they will clear on you

tehn Raph onwards try to stick to the x4 with 3 additional lines for a total of 6

Timings:

If you are short, you might want to work on your initial attack on those first 9 seconds to ensure you get a big enough attack, dont be afraid to chain big if you need to.

You will see many kills between 10-14 if you first send is good and 15 if your back up is good.

If they are clearing empty blocks you will see clears at 17-19 and if they clear your garbage once you should be done in 21 seconds.

Getting that consistent start for the first 9 seconds is crucial for this strategy which is why combo weaving is essential and lag chaining is very desired
