It is not, there are two parts to the buff, although only one is shown as an actual buff on the affected unit. Both are reapplied for the whole continuation of the spell, but after it ended only one part of it sticks for 10 seconds the other does not. Discovered that in the tool and tested it in the forge. Test for yourself if you want

NAME: Ironclad (red)'s damage against frozen aura continues after it finished the abbility, but only part of it DESCRIPTION: This is a special one. Ironclad (red)'s aura when using its ability has two parts: Ignore the 50% frozen reduction and increase the damage against frozen targets by 50%. So when attacking a frozen target other units deal 150% of their base damage during Ironcald's cast. After the cast the buff persists on friendly units for 10 more seconds, but only the second part. The frozen reduction ignore is lost directly after the cast. So during those 10 seconds friendly units deal 75% damage against frozen targets. Either let both parts of the aura persist 10 seconds after cast or neither. REPRODUCIBILITY: can be tested with every friendly unit against a frozen target.

I'm doing the testing on the test server, so maybe it's correct on live... But I used the tool to confirm my findings and I assume the tool has what is live on both servers right now.

NAME: Tempest U3 doesn't deal double damage against frozen targets like all Upgrades before DESCRIPTION: So Tempest U0-2 deal double damage against frozen targets and with the 50% reduction of freeze they deal their base damage per shot against frozen targets. U3 doesn't. At U3 it deals 50 against unfrozen targets and only 48 against frozen targets. REPRODUCIBILITY: let it attack a frozen target at U0-U2 and see their normal damage, at U3 though it's only 48 damage. ADDITIONAL_INFO: After looking in the tool I saw that it applies a second instance of damage against frozen targets with the same strength as the base damage. Atleast for U0-2. At U3 the second instance only deals 46-70 damage thus resulting in the 48 (= (50+46)*0.5) damage against frozen targets.

NAME: Winter Witch U1 uses Gift of Winter of U2 DESCRIPTION: The shield given by Gift of Winter on U1 is 1800 even though it should only be 1500. It's not only the description on the buff but also the actual value. REPRODUCIBILITY: activate gift of Winter U1 on the winter witch and walk out of the circle. Only after 6 Eruptions the shield is gone (6*300=1800)

NAME: "Mo's better blues" of Promo Mo only increases damage against units by 50% DESCRIPTION: "Mo's better blues" of normal Mo increases damage by 50% against units and structures but the same ability of promo Mo only increases the damage vs units REPRODUCIBILITY: Fallen Skyelf (100 damage per attack) with the buff from normal Mo does 150 Damage against units and structures. With the buff from promo Mo it's only 150 against units and 100 against structures

NAME: Core Dredge (blue) U3 doesn't deal increased damage against frozen buildings with Shatter Ice DESCRIPTION: When freezing buildings with Rageflame (red), then Core Dredge (blue) U3 only ignores the usual damage reduction of the frozen building but doesn't deal 50% more damage. That 50% works against units. Cards like Northstar and Lost Wanderer (blue) also increase the damage against frozen buildings (not only ignore of the damage reduction). REPRODUCIBILITY: freeze building with rageflame (red) and walk away with the card, attack with core dredge (blue) U2 (deals 200 damage with one hit), tower takes 200 damage, but should be 300.

Yeah it's a descriptive error, it attacks like frost mage, so in a line and not like a splash at the target. That descriptive error is already noted

NAME: Frontier Keep (red) casts it's ability twice resulting in unfrozen units showing the 'resisted' text DESCRIPTION: When using the ability of Frontier Keep (red) all units hit (regardless of if their unfrozen or frozen) show the 'resisted' text. I think that is because the ability is cast two times in a row with a really really small delay. REPRODUCIBILITY: summon Keep, summon enemy, use ability

NAME: Shrine of Martyr's global buff shows with a red border even though it is my own building DESCRIPTION: As the title says, the global buff of Shrine of Martyr shows as an opposing global buff even though it is your own. REPRODUCIBILITY: summon tower, activate ability (ingame)

NAME: Moon applies the dark arts ability twice in a row DESCRIPTION: normally it should be 3000 hp from corpses converted into 6000 healing for units. But when testing with a Spore Launcher at 100/8300 hp and a dead spore launcher to the side the ability healed the spore launcher back to full in two ticks (~0,5 secs delay). More testing showed that it just activates twice in a row, so taking 2x3000 hp from corpses to heal 2x6000 hp for units. REPRODUCIBILITY: 3 Spore launcher on low hp + Moon + 6000+ hp corspes => Moon heals the 3 spore Launchers for 4000 hp each

NAME: Ice Age (blue) applies the shield restore twice DESCRIPTION: the 800-1000 shield restore that gets applied on all ice shields when casting Ice Age (blue) is applied twice in a row (~0.5 sec delay). REPRODUCIBILITY: get a Ice Shield over 1000 (winter witch, or Avatar of frost work) and low enough that it wouldn't be full with one restore. Cast Ice Age and see the ice shield max out. To perfectly see it use the avatar of frost U3, hit him with Inferno U3 and activate Ice Age (blue). Inferno puts him at 100/2500 shield and ice age restores back to 2100/2500 (timing is iffy with avatar of frost's passive though)

NAME: Mountain Rowdy (blue)'s Ice Block ability actually has a 30 sec cool-down instead of 15/20 sec as the card says (and as the other affinity has) DESCRIPTION: The ability has an actual cooldown of 30 seconds. Description says it should be 15/20 (U0+1/2+3) which matches the other affinity (that one has the actual 20 sec cd). REPRODUCIBILITY: use the ability and use a timer (30 sec on all upgrade stages)

NAME: Mountain Rowdy (both affinities)'s Ice Block ability has a 20m radius (in text and actually) but the the circle on hover is only 15m DESCRIPTION: The ability has an actual range of 20m and that's what's written in the description as well. Just the circle that's shown on hover is too small (only 15m) REPRODUCIBILITY: hover over the ability and compare with the circle from surge of light (that one is 15m)

NAME: Northstar (green) gives Ice Breaker buff to itself, the other affinity doesn't (low priority bug) DESCRIPTION: The two affinities of Northstar behave differently. One give the "damage against frozen"-buff to itself the other one doesn't. Gameplay wise it's not important since both don't do any damage, but regarding consistency smth can be gained here. Going by the description ("...all Friendly Entities...") the Northstar (green) behaves correctly and (blue) needs to be changes REPRODUCIBILITY: Just spawn them alone and look if it has the buff. The green one has it, the blue one doesn't.
