40% health of 770 is 308.
The most exaggerated level 3 cheese combo, which assumes the Tryndamere is a fool and does nothing and just lets Talon hit him for free, step by step:
- Talon's E slows by 99% for 0.25 seconds and makes him blink behind Tryndamere, amplifying all damage dealt by 3% for the next 3 seconds (does not affect Ignite). We will assume the Talon player is able to achieve his combo within 3 seconds for the purpose of this demonstration.
- Talon autoattacks regularly. (59.8+10+8.55+6.75+3.32=88.42) His passive increases the damage by 10%, his E increases the damage by 3%, Assassin increases the damage by 2%, DES increases the damage by 3%, and Oppressor increases it by 2.5%. Thus, the damage from this auto is 88.42 x (110% x 103% x 102% x 103% x 102.5%) = 122.008805% modifier, which makes the autoattack deal 107.880185 damage before armor. And then Tryndamere's DES factors in, which increases the damage by 1.5% to 109.498388. Tryndamere has 37.7 armor, while Talon has 3.9 armor penetration, effectively making Tryndamere's armor be worth 33.8. This makes the armor effectively change the damage multiplier to 0.747384155 (74.7384155%). So Talon's autoattack deals 81.8373602. Tryndamere has 688.16264 health left. The slow from E has ended.
- Talon hits you with Rake for 30 damage per pass + 60% bonus AD. So 60 + 120% bonus AD just from the W, which amounts to 60+34.344, which equals 94.344. His E modifier increases by 3%, Sorcery increases by 2%, DES increases by 3%, and Assassin increases by 2%, and Oppressor increases by 2.5% which makes the end multiplier be be 1.13135437 multiplier (113.135437%) Thus, it deals 106.736497 damage before armor. The 1.5% additional from Tryndamere's DES increases it to 108.337544.
The armor pen vs armor multiplier, like before, is 0.747384155. Thus, Talon's Rake deals 80.9697638 damage after hitting both passes. Tryndamere has 607.192876 health left.
- Talon hits you with another auto, which deals 81.8373602 (like before). Tryndamere has 525.355516 health left.
- Thunderlord's goes off for 30 (10 x level) + 8.586 (30% of bonus AD) + 0.501 (10% of bonus AP, said AP being from Natural Talent) damage which equals 39.087 damage. Tryndamere has 33.9 base MR at level 3 + 9 from Glyphs, making it 42.9 effectively. Now, Talon's various factors include Assassin (2% increase), Precision (3.9 MPen), DES (3% additional), and Tryndamere's DES (1.5% additional to him). 42.9 MR becomes 39 MR effectively with Precision's MPen. 39.087 x (102% x 103%) = 41.0648022. 41.0648022 x (101.5%) = 41.6807742. The MR multiplier is effectively 0.71942446, making Thunderlord's as a whole deal 29.9861685 damage. Tryndamere has 495.369347 health left.
- Talon resets his autoattack with his Q and hits you again. The autoattack deals 30+30% bonus AD as bonus physical damage initially, which is 30+8.586 which equals 38.586 bonus damage. Thus, Talon's auto deals 38.586+88.42 damage before multipliers, which results in 127.276 damage. Talon's own multipliers increases it to 155.287927, and Tryndamere's DES increases it to 157.617246. The armor reduction reduces it to 117.800632. Tryndamere has 377.568715 health left.
- The bleed from Talon's Q deals 1.7+(16.7% bonus AD) per second for 6 seconds. I'll be generous and say both of the first 2 initial ticks get the Oppressor increase (saying that the autoattacks from both after the Rake took 0 seconds). A tick deals 6.47954 damage before multipliers and armor/armorpen. His multipliers increase it by 1.0984023x, making it 7.11714164 per tick. Armor reduction vs pen changes it to 5.31923889 per tick. So the first two ticks deal 10.6384778. The next 4 ticks equal 6.8+66.8% bonus AD which equals 25.91816 total. The multiplier here is 1.071612 which makes it deal 27.7742113. Armor reduces it to 20.7580054. Tryndamere has 346.172232 health left.
- Around the same time, Tryndamere would have been Ignited, which would deal 50+(20 x level) damage. Which equals 110 damage. 346.172232 - 110 = 236.172232
If you want to be super technical and go by each individual tick to see when the 'below 40% health takes 5% increased', here we go. I'll even be generous and assume that Ignite tick goes off before the Q tick so it'll trigger the Q proc faster. Each Ignite tick is 22 damage (110 divided by 5). Tryndamere's Health before the ticks on either start is 377.568715. Ignite is not affected by damage altering sources.
Ignite tick 1 is 377.568715-22=355.568715
Q tick 1 is 355.568715-5.31923889=350.249476
Ignite tick 2 is 350.249476-22=328.249476
Q tick 2 is 328.249476-5.31923889=322.930237
Ignite tick 3 is 322.930237-22=300.930237
The cutoff has been reached, as Tryndamere's health at 40% is 308.
Q tick 3 would have the multipliers of Sorcery, DES, Assassin, Merciless, the Tryndamere's DES, and be affected by Talon's armorpen and Tryndamere's armor. The relevant multipliers are (102 x 103% x 105%) for Talon's, which places the Q tick damage at 6.47954 x 1.10313 which equals 7.14777496. Tryndamere's DES puts it at 7.50516371. Armor puts it at 5.60924044. Anyways... continuing on.
Q tick 3 is 300.930237-5.60924044=295.320997
Ignite tick 4 is 295.320997-22=273.320997
Q tick 4 is 273.320997-5.60924044=267.711757
Ignite tick 5 (Final Ignite tick) is 267.711757-22=245.711757
Q tick 5 is 245.711757-5.60924044=240.102517
Q tick 6 (Final Q tick) is 240.102517-5.60924044=234.493277.
Even with Merciless factored in, there's barely a 2-3 health point's worth of damage in difference.
That is nowhere near 0.
You are incorrect, and either are flat-out lying through your teeth, or exaggerating through faulty memory/anger/salt.
